The old Geophysical Laboratory on Upton Street

Geophysical Laboratory early 1900s

            Built in the early 1900s, the Geophysical Laboratory, two blocks off of busy Connecticut Ave. in Washington, DC, was designed specially for sensitive temperature measurements important for determining how the interior of the Earth was structured. The Laboratory’s interior walls were 18 inches thick (about 40 cm) and the exterior walls, at least two feet thick. Perched on top of the 2^nd highest hill in Washington (the National Cathedral is the highest), the Lab commanded a view of much of downtown D.C. through the filter of tall trees that graced the grounds. I first saw the Lab in July 1977, a couple of days before starting my postdoc. It was the 4^th of July weekend, so I was to start work immediately after the holiday. My friend Nancy “Nat” Peters drove me by. We stared in awe of the august building. I was humbled.

            When I arrived for work a day or so later, entering into the double doors of the main entrance, the 1^st Floor hallway was eerily silent. Wooden museum cabinets flanked the walls containing mineral specimens that had been given names in honor of the famous scientists who had worked at the Geophysical Lab. I reported first to Tom Hoering in his office and lab suite on the 1st Floor. Hoering’s office centered on his old oak desk and was flanked on either side by lab benches holding a balance for weighing, a small refrigerator, and two gas chromatographs. He loved being among the hum of instruments, even in his office. The main lab held three mass spectrometers—an old homemade instrument, a new Nuclide mass spectrometer to measure hydrogen isotopes, and a 3^rd mass spectrometer for measuring the chemical structures of unknown compounds from sediments, oils, and rocks. Lab benches by the front windows were covered with custom made glass vacuum lines with columns of liquid mercury, pumps, and furnaces. A smaller interior lab included two ancient, soapstone hoods that barely worked, a bromine-pentafluoride vacuum line, and the laboratory bench that became my “home” for doing research for the next several years.

            After a brief meeting, I was taken to the 2^nd Floor where the Director had a suite of offices and the secretarial staff was located. In those days, people used telephones and letters to communicate, rather than email or text messages. Secretaries answered most phone calls, then used a complex series of bells to summon us to answer the phone. My call sign was 5-1: ding ding ding ding ding pause ding. Hoering’s was 5-2. When we heard five rings, we both listened up. The secretaries also typed all of our manuscripts and correspondence. They were sources of important information on how things really worked.

            I was assigned a desk space at the other end of the hall from Tom’s lab, just outside of Larry Finger’s crystallography laboratory on the 1^st Floor. With tousled curly brown hair and a matching beard of a similar unruly nature, Finger had designed an automated laboratory with two or three sophisticated X-ray instruments specially designed to measure the crystal structure of very small pieces of common and rare minerals. He was an early computer whizz. His inner office, stacked with paper computer codes, punch cards, and various computer parts, was the typical scientific mess. Larry was assigned the job of computer support for the Lab, which took up a considerable amount of his valuable time. Often he was seen as a grumpy tyrant, but in reality, he was very generous with his time and knowledge.

            Over the next few years, my Lab “real estate” expanded from the Basement all the way to the Attic floor. To sterilize the media for my microbial cultures, I used an autoclave—a large, hot, pressurized cylinder that was installed in the basement room where the maintenance staff ate their lunches and changed their clothes. When I was coming down the spiral staircase into this room—the support staff lair--I whistled so that I wouldn’t literally catch them with their pants down. One floor lower was where the Boiler Room and Electrical Vault lay. The Lab’s only shower, peppered with mold and grime from years of neglect, was located on this level. The few women at the Lab rarely, if ever, used it. The Electrical Vault doubled as a Barber Shop, run by our mail clerk, Harvey Lutz. Budget conscious staff scientists had their hair trimmed there on a regular basis.

            The Attic was a similarly unusual place that served many purposes. It housed a storeroom of used glassware and chemicals, a dark room for processing photographs and slides, an archive of old papers, a museum-like office with former staff member Frank Scheirer’s pipe, desk, and papers, and a small room that I used for transferring microbial cultures. When any postdoc needed a few beakers for an experiment, she/he was sent by Dave Singer, the Assistant to the Director, to the Attic to see if some could be found in the jumbled storeroom. The storeroom held a treasure trove of old historic junk, including all of the radioactive samples analyzed over the Lab’s history.

            In order to maintain sterile conditions, I needed to shine ultraviolet lights on the bench tops for 8 hours prior to working. Here was my routine: 1) make the culture media in my lab on the 1^st Floor; 2) carry it and the glassware for growing the microbes into the Basement where it was sterilized; 3) bring it up to the Attic for inoculating with microbes; 4) carry down the cultures to my lab on the 1^st Floor. Hardly convenient, especially since the Laboratory had no elevator!

            Tucked underneath the stairs on the Ground Floor, Doug Rumble’s small lab housed the Nuclide isotope ratio mass spectrometer we shared. I would prepare samples in my 1st Floor lab, then shuttle them downstairs for final analyses. Our gas tanks came into the Ground Floor from an adjacent parking lot. When we needed one upstairs, our janitorial staff used an old-fashioned dumbwaiter to physically haul it up. The instrument shop took up much of the real estate on the Ground Floor. Employing three to four machinists at any one time, the Shop could make any complex metal structure you could imagine. Having this facility on site made the difference for most of the Lab’s scientists, who designed their own specialized equipment. The men’s only restroom was on the Ground Floor and was the only restroom in the building when it was built, meaning there was no ladies restroom! Sometime in the 1930s, a Ladies room was built on the 2^nd Floor.

            The rear of the Laboratory held three external, separate buildings—the Dog Sheds, low “temporary” laboratories built for research during World War II; the Electronics Shack, housing our electron microprobe; and a metal shed holding years of old, often-leaking chemicals. Rus Hemley managed to build a nice lab in the Dog Sheds that overlooked the volleyball court, that was outside the Dog Sheds and actively used for games at lunchtime. We also used the court for disposing waste bromine pentafluoride, a nasty explosive chemical reacted safely with the water vapor in DC’s humid air.

            The exterior of the Lab was tan stucco, with a very distinct patch on the side that was replaced after a serious fire. Two tall holly trees dwarfed the front flanks of the building. Rambling roses covered the front entrance giving the appearance of a modern day Sleeping Beauty castle. Azaleas imported from Japan by visiting scientists rimmed the front lawns. We held picnics and barbecues there, as well as the Friday afternoon beer sessions. A curving driveway swept up from Upton Street in a loop. It was not that unusual for someone’s car to roll off the driveway into the lawn because their parking brakes weren’t set.

            In photos of the Lab when it was first built, all of the trees were small saplings. A large weeping willow, planted by staff member Joe Boyd to hide the electrical lines, frequently took out our power at the first sign of wind or a thunderstorm, something that happened almost weekly in the summer. The saplings grew into massive oaks, maples, and walnut trees. In one of the massive storms that swept through the area, postdoc Zach Sharp and I watched from the front doors as tall trees were completely uprooted, flying like tooth picks under the influence of the violent winds. The grounds were nearly destroyed; electric lines were downed. A large, uprooted walnut tree at the rear of the Lab was recycled one weekend by my husband Chris and postdoc Susse Wright’s husband Tom. Tom Wright, an NSF program director, grew up on a tree farm in Alabama and had a chain saw. He and Chris sawed off the limbs, loaded the heavy trunk onto the back of Chris’s Jug Bay Wetlands Sanctuary work truck and took it to a small sawmill in southern Maryland. We have a picnic table built with the lumber and shared some of it with others at the Lab. I cherish it as a memory of that day and of the old Upton St. Laboratory.

            Without question the old Geophysical Laboratory building had history, class, and a unique character. We all loved it, but eventually it began to limit our scientific research. The electrical system was a rat’s nest. My laboratory had power lines coming in from three sources, one of which ran through the Instrument Shop. When they turned on a certain milling machine, one of my mass spectrometers would catastrophically shut down. We didn’t have enough space for new equipment; if we did, it often got stuck on the stairways bringing it in. NSF refused to fund a new mass spectrometer we desperately needed until we moved to the new lab. The fume hoods could no longer handle the chemicals we were using. The DC Environmental Protection agency was appalled at our old chemical storage shed. In summer time, the room air conditioners were insufficient to cool labs. In winter, the old boiler often broke down for days at a time. The Lab was contaminated with radioactive carbon, so our work on dating bones needed to move to the National Bureau of Standards. It was time for a change.

            In 1990, we moved to 5251 Broad Branch Rd., N.W. campus amid a flurry of activity. Ed Hare claimed he wouldn’t move and refused to pack up his lab when the moving trucks came. The Laboratory photo that year showed us all in our work clothes, informally posing on the front steps. Tom Hoering worked so hard, he took naps on cardboard spread out on his old lab benches, now vacated. The move took over two weeks. When it was over, we came back to see the bones of our beloved building. Even today, when I dream about the Geophysical Lab, which I do often, it’s always the Old Lab that I dream about. Memories of the old Lab are dear to many.
