Searching for Lulu at the Inauguration

January 22, 2009

Searching for Lulu

After three hours of standing on the frigid ground, the circulation in the feet slows, the sludge of 50 weight oil sumps in ankles, and stasis creeps up into knees. (The cold still grips the calves, even days later.) Stamping feet to get blood moving, we listened silently to the speeches and, as the words dissolved into the air, we were led, and sometimes pushed, towards an indiscernible exit, ebbing as a tide caught between shore and some unseen reef.

We headed back towards the outdoor johns and where we had entered the assembly ground earlier that morning. We knew to move towards Georgetown, to eventual escape but through an uncertain passage. I know now a little of how a salmon feels, being routed through a fish ladder, except you can’t jump over the other fish here; it’s push and a pull, no leaping. You go with it.

Lulu’s grandmother did.

Standing shoulder-to-shoulder during the ceremony embedded within people of all makes and models for a few hours makes for an interesting community immersion. Characters define themselves and unintentionally emerge: The guy with the round glasses behind, booing each representative of the old regime appearing on the “Jumbotron”; the short gal with the white fuzzy hat and yellow coat that jumped up and down to see over the sea of shoulders; the proud many living their grandparents’ dreams; the colorful couple to the right that nuzzled and tried to stay warm, one clearly very interested in the other—the rest of the world was invisible.

For a few hours, a mass of humanity unimagined in any place—sporting events, shopping venues, even the Beijing subway—were connected. No, not simply connected, sewn together and made a knit of every possible variation of God’s design. A giant crazy quilt of color, size, background, motivation and satisfaction.

The cold limited conversation to a degree although we huddled for warmth: a pack of penguins in parkas. The stentorian audio mortared the gaps between the attendees, sometimes emitting curious sounds: whispered hellos and comments from the dais, the whooshing of the moment through microphones as the wind rose through the tunnels where high-and-mighties (and wouldn’t we give a right arm to be them) were teased out from their warm cars and limousines to the cold and into the New. Other times, casual human conversations are captured: “It is nice to see you again,” said the Senator cum-Secretary to the aging, retired President. We listened closely.

In our immediate crowd, a young man from Mumbai (maybe Chennai? I didn’t ask) waved his flag behind me, his eyes wondrous but uncertain what to make of all this. During the peak of the excitement (and lo, the shrieking was mostly the province of the young women), the enthusiasm and excitement electrified the crowd.

And so it came to pass that the long wistfully-wanted achievement was made and our part was played (to its fullest). It became time to detach and return to some warmth and our daily deeds and wonder about during our reflective moments that which we had just witnessed. [And the witnesses all nodded to each other and said without words: “Yeah, I understand.”]

Here’s a little “shaky cam” of the zenith:

We left in near silence, absent celebratory whooping or hollering, imbued with the sense of leaving a somber Church service. Or were we just all friggin’ cold?!

458609844_dsc_01461

Out to the exits and through strangling gates, our legs regaining flexibility and warming slightly, our thoughts still simmering. So we, the bit players, the chorus, the gallery, moved out.

We strode west and Zacchaeus’s climbed the short denuded cherry trees to get a look over the heads of the parkas and scarves. A few of those who took a precarious refuge were content to load the branches: two lovers traded a sandwich on their flora floes and laughed between them as the crowd weaved by; they were lost together in their shared elevated space. Others in the cherries purposefully scanned and gave directions, gravely, and accidentally, conscripted by their position to give commands to the crowd. One, wearing a brown jacket and bright orange knit hat and ski mittens—the kind favored by snowboarders—rose on a limb and looked down and to the left, gesturing to those around. He was spied immediately, like a traffic cop in the middle of a hurricane.

“Tree-MAN!” someone entreated. “Where should we go?”

Tree-Man, resolutely, and bravely waved the colors, or, rather, his gloves towards the South. “It’s there, I mean, head THAT way.” With a gesture he lay the way forward, to the left of the natural flow of the crowd. Ah, there, maybe, some unrestricted, some uncontrolled escape, and some relief lay. It was south and so we would do it. And so, on Tree-Man’s word, whole swarms of people moved in that direction, heeding his vision from his perch, but mostly, relying on his certitude.

“Keep moving left, Dad.” My own charge directed and set out at a thirty degree angle from our path, towards some open space.

“Alright, alright. Just be patient. We’ll get there.” Moving with the swarm, lemmings leapt to mind. Then again, even in their supposed behavioral folly, lemmings…have long survived.

Closer to our short-term goal, others climbed atop the porta-potties and danced from white roof to white roof, finding an expressway above the mob. We laughed: so brazen, so ridiculous. Would we have the guts to do the same anytime in our lives? Two port-a-pot leapers chose to take up uncertain positions atop the noisome things (it was too cold to notice, I think) and waved to those who would pay heed—their own part of the throng—around the “necessaries,” one affirming Tree-Man’s anointed safe escape, the other indicating a contrary direction. We chose to follow two-out-of-three unsolicited directions.

man-on-dons-johns

We found ourselves half-way through and a grandmotherly lady wearing a long brown fur coat around her body and a round hat (matching) on her head moved tentatively over the brown chalky ground. She was walking with her arm around another lady’s, who had taken her and was talking friendly and slowed her own pace solicitously to match the old woman’s.

Amidst all this company, the old lady had lost her group and, in this kind of crowd, someone who was lost alone and old could have had a life’s dose of fear and near-panic. Instead, a Saint took her arm; in this gathering, malice was absent.

A few dozen paces passed under their joined step when the younger woman’s companion, a man of forty-four or forty-five leaned in to the older lady: “Give me a name, dear.” He took two paces. “Who did you come with?”

“Lulu.” She said quietly, barely audibly. “Lulu. She’s my grand-daughter.”

“Lulu?” Repeated the man. She nodded. Then, taking two big steps, he cleared his throat and addressed the sea of people with a loud “LOOO-LOO!” Again, and towards his left: “LOOO-LOO!”

Heads swiveled and looked his way, but there was no reply. The plodding pace of the crowd advanced. There was only one way Lulu would be found in this crowd: by grace.

The hero kept at it: “LOO-LOOOOO! Your grandma is looking for YOU, GIRL!” The Samaritan yelled with an enviable lack of self-consciousness.

We walked and scanned the crowd. People moved to the crowd’s cadence, but no raised, gloved hand appeared.

“Loo-LoooH?” One more time. We looked around. Still, except for the breathing and the walking.

She gripped her escort’s arm. “That’s alright. I’ll find them. They’ll find me.”

Grandmother trudged steadily but without weariness, the day’s pride warming her from the inside, a stranger’s comfort fast around her arm.

IEEE EMC Founders Found

Leonard Keeps Giving: Another Dig Into The Past

Mike Violette

About thirty minutes from the National Archives is a humble storage complex at Tysons Corner, an architectural inversion of the federalist-style granite building that cradles the scriptures from the founding of our country. For the EMC Society, this humble Virginia facility holds the recovered scrolls from our early summer trip to Leonard Thomas inner sanctum, a critical link to the history of our groups founding.

As Summer reluctantly left the stage to Fall on a brilliant blue-sky Friday, Dan Hoolihan, EMCS Historian, continued his hunt for the near-legendary, possibly mythical list of the names of the original EMC Founders. Words have been whispered, theories proposed and emails exchanged: somewhere in the first secretarys earthly possessions was that fabled List. That morning, fortified by a life-shortening, but delicious egg and sausage and swiss cheese breakfast sandwich, lovingly assembled on a fresh multi-grain brioche and washed down with a truly above average cup of coffee, we advanced like knights in search of the Holy Grail, but with maybe less ecclesiastical fervor and certainly less clunking, and not on steeds, but in four cylinder sedans.

As traffic in Tysons wound up to its usual frenetic and loathsome neck-muscle tightening swirl, we set forth off to find it: The List.

ieee-emc-founders-found_img_0

Once again, we found much more.

Dans reverent guidance was simple and direct, I posit not unlike Lewis Leakeys gentle words to his staff as the first indications of the fossilized bones of Australopithecus afarensis or Lucy were swept clean of eons of limbo. “Careful lads,” I imagine him saying. “The smallest scrap might hold the biggest clue.”

Maybe we would be as lucky and our Lucy would be brought to light. It was with measured optimism that we pulled into a cookie-cutter orange storage company where people keep their treasures that they rarely visit and have mostly forgotten: toys they no longer play with and clothes that dont fit and appliances that will never again feel a crackling glow in their electrical circulatory system.

Not unlike Howard Carters feeling of elation upon discovering the resting place of Tutankhamen (ok, ok its a stretch), we gently coaxed the cypherlock open.

With a soft click the door yielded and we entered the climate-controlled tomb of unloved prized possessions.

With a clattering rattle, the overhead metal door was flung open and light bathed a wondrous scene. We had to pause and catch our breath, brows wet, despite the conditioned air of the place. My nostrils filled with the sweet smell of timeless nostalgia; the air swirled mysteriously overhead as a motor kicked to life someplace (did I catch a whiff of mimeograph ink?). I reeled for a moment. In those lovely white cardboard sarcophagi was the march of time, possibly five decades or more: pencil, pen, carbon paper, Xerox, thermal facsimile, so many ways of communicating.

Again back to Carter: I imagined him studying the cuneiform and hieroglyphs under flickering lights. If only we could douse the glaring incandescent lights and hold torches to our treasure, we might then understand fully that thrill.  Unfortunately, the Fairfax County Fire Department generally frowns upon the possession and burning of kerosene-soaked torches in enclosed spaces.

The Forties

We set to work, opening the boxed files as hundreds of voices of EMC past fairly chattered. We searched each and every file in pursuit of the List. At another time, with more leisure, each set of documents could entertain and inform for hours. But time was against us.

Did we fear that the precious documents would crumble to dust? Or was there a meticulous but benign spirit whose essence shadowed the fifty years of carefully-typed minutes and meetings? Did the engineers who invented the devices in the catalogs and specifications cry out in haunting voices: “Remember My Oscillator. I Have Created It!”? Or did we feel the ghost of a WWII Navy Technician, forever bound to the Earth, hopelessly searching for the Spare Parts Catalog for Panoramic Radio Receivers, published nineteen forty five? No, no–No such thing, all imagined.  Dan had to hop a plane at noon.

The Fifties

Advancing my search a decade and more than slightly off-task, I marveled at the deft innovation of the motor-operated “Mechanical Sweep Drive” from the General Radio Catalog which “attaches to knobs, dials or shafts” to speed EMC tests. Even in its infancy, a certain tedium accompanied our work. Confession: It has not been too long since we rigged an electric drill to our venerable HP 8672 signal generator to accomplish the same thing. (And a paper clip jammed in the frequency increment button does the trick on an 8656.) As to the frequency standard, I cant imagine calculating the uncertainty accompanying a calibration on the four hundred pound, seven foot rack of wire, knobs and tubes.

ieee-emc-founders-found_img_7

A third box produced a yellowing kraft-paper envelope which granted us some more gold, complete with black and white photographs. Locale: off the coast of California. Maybe a studied propeller-head reader of this journal can weigh in on the make and model of the airplane while the rest of us can marvel at the RF rig that this young engineer is using to do his EMC thing. Check out the “graphical interface”: pre-pandisplay; pre-Polaroid; post-papyrus.

ieee-emc-founders-found_img_8

Were not sure who this pioneer is (Leonard, himself, perhaps?), but the caption of the photo reads “ambient test” and this particular project looked like a site survey or RF system performance measurement of some kind; in the envelope were multiple aerial photos taken through the window of the small tail-dragger in the background.

The Sixties

The US was firmly in the grip of the hysteria of the Cold War and apocalyptical fear gripped the pen of the author of the article on EMC in the New Englander, a general-interest publication. In the October 1963 edition it carried an ominous article on EMC, likening the problem of RF Interference to that unveiled in Rachel Carsons book of that time on the environment: Silent Spring. The bent of the article was that the uncontrolled growth in radio frequency emissions was going to leave the spectrum a hostile and toxic place. There are some amusing snippets in the piece, including likening RF propagation to nuclear fissing, to wit:

“…when the static energy travels and snowballs, picking up more energy and gathering strength as it goes, ending up miles from its original source, that can be dangerous…” Hmmm.

And “Another Silent Spring may be in the making.” Yikes! The article goes on its exposé of the various levels of interest, ignorance and denial that are the human condition, and again, the more things change..“ As a result of mans inventiveness and passion for miniaturization, products emitting electrical energy have been made even smaller and smaller–and packed closer to other sources of spurious emission”

and finally, a time-proved statement:

“The FCC staff is overworked and understaffed.”

In the fine but faulty rhetoric of the Post-McCarthyera, it speaks of “an EMC-riddled atmosphere.”

If that were true, wed all be looking for jobs. Too much EMC? Let us pray not!  But smug observations aside, its an interesting read, for sure, and talks about the origins of the Electromagnetic Compatibility Analysis Center (ECAC) in Annapolis. One interesting paragraph harkens to the early formation of the EMC Society. “…in 1957 the Professional Group on Radio Frequency Interference of the Institute of Radio Engineering was formed and has now changed its name to the Professional Technical Group on Electromagnetic Compatibility (PTGEMC) in order to include the entire interference field.”

The Seventies

But before we advance to the present, we have to pay homage to one more decade. Tripping along through the sixties we welcomed the engineering community to the summer of Love and and the Groovy EMC Society with the “1970 International Symposium on EMC”. That is some Aquarius cool, the Expanding Science of EMC. WOW! Lets jump in the hot tub, celebrate the next few decades of discovery (and hope theres no leakage current). Aha! Another click of the Rubiks Cube. We cant be far-off…

ieee-emc-founders-found_img_3

Engineers in bell-bottoms.

Far out!

Our Plutarch remained steady at his task and muttered quietly, reading off the names of the Founders and followers of the EMCS,lost in a certain reverie as he scanned minutes of years of meetings and various correspondences, reading the names:

Fisher, ONeill, Nichols, Kesselman, White,Showers, Heirman, Schlicke, so many others.

We must be close to finding the Keystone.

ieee-emc-founders-found_img_4

Meanwhile, I had the good fortune to sift through some of the collection: correspondence, professional and semi-personal collections of articles, standards and publications.

The first ANSI C95.1 was about five pages long. Ten milliwatts per cm squared.

ieee-emc-founders-found_img_5

Curiously, a letter written to a young Mr. Thomas slipped from a manila folder and floated to the floor. Dated March 18, 1949 on Bell Telephone Laboratories letterhead, carefully typed on a Remington or Smith-Corona Manual, it read, in part. (Iimagine Leonard s thrill: Ah, publication!).

“Dear Mr. Thomas, I am glad to inform you that your paper “Interference Reduction” has been accepted for presentation at a meeting sponsored by Commission 4 of the URS in Washington on May 2-3. You will be informed of detailed arrangements later.

ieee-emc-founders-found_img_6

Interference? Back in 1949? The transistor was still in swaddling clothes! But, I am reminded: The more things change, &c. And as to the pursuit of the paper: “Interference Reduction”, truthfully, I am not unhappy that Mr. Thomas paper did not reduce all of the interference, for, lo it is often a lonely and painful pursuit, were it not for interference, we would not be slabbing words on a page for Ms. ONeils journal.

List Ho!?

At this point, our time was running out and we hadnt found what we were looking forand the effects of the mornings coffee had worn off. We decided to stop after one more box and leave the rest to another time when fortuitously a folder with title: “EMC History” was pulled from the fourth box.Dans hands trembled as his eyes fell to handwritten sign-in sheets and finally, perhaps, the Grail itself–a transcribed list of names on graph paper.

“I think we may have it,” Dan said, his laconic mid-western manner thinly and insufficiently covering his excitement. “Ill write this down and see if our members recognize these names.”

pages-from-ieee-emc-founders-found_img_1

Buoyed, but cautious, we re-sealed the tomb and left, vowing to return and sift through the archives once more, should our mission not be complete.

Dan made his plane.

Thanks again Mr. Thomas.

Epilogue

Well, is it the list? Dan, what did you find?
