Thomas B. Greenslade Jr. and scientific instruments

I wonder if Thomas B. Greenslade Jr. knows Richard Zitto...a fellow science instrument collector. When I was working in radio, the station needed to replace the transmitter's broadcasting vacuum tube. Egads, $20,000. Wish I had it and my whole vacuum tube collection back.

"Antique devices get his heart pumping"

When Thomas B. Greenslade Jr. is talking about his collection of antique scientific instruments, it's best to hang on tight.

He speaks in a flurry of "horizontal galvanometers" and "double reciprocating motors," with a lot of "oh, by the ways."

When I asked about one device, his answer encompassed X-rays, Australia and the fact that the world has four places named Gambier, all of them named for "a very boring, extremely pious and rather inept British admiral."

The man knows his stuff.

Greenslade, a retired physics professor at Kenyon College in Gambier (the one in Ohio), is an expert on scientific apparatus built between 1850 and 1950. The Smithsonian comes to him for information.

He is a sort of rescue service for vintage oscillators, induction coils and magnetometers. College physics departments call him when they're cleaning out their attics.

How did he get a vacuum pump from Westminster College in Pennsylvania?

"I gave a lecture there. . . . They asked, 'Would you like a stipend, or would you like some apparatus?' "

How about an 1880s direct- current meter? Someone at West Virginia University gave it to him, lest it be tossed in the trash.

"It was passed on to me in a parking lot in Greensboro, N.C., at 10 o'clock in the evening."

Greenslade taught physics at Kenyon for 41 years before retiring (for the second time) in 2005. He and his wife, Sonia, still live on the edge of campus in a house with one large room devoted solely to his extensive collection.

It has proved visually arresting enough to attract the attention of artists. Several of Greenslade's devices are featured through Feb. 28 in a small exhibit in the Olin Art Gallery in the Kenyon College library.

The exhibit, by Gary Nickard and Reinhard Reitzenstein, both art professors at the University at Buffalo, combines objects from science, art and nature. It's a 21st-century take on wunderkammern, which were Renaissance-era collections of curiosities from throughout the world.

Nickard said Greenslade's gadgets astounded him.

"He has probably one of the most formidable collections of antiquarian physics instruments that I've ever seen. It was mind-blowing."

The artists picked the devices solely for their beauty, then displayed them with birds' nests and sculptures. So one of Greenslade's instruments has a stylized insect resting on top and a nest nearby. As we studied the display, the professor said he gets it -- sort of.

"At this point, I realize that the scientific mind doesn't understand the artistic mind, and the inverse is true. But we coexist very nicely."

Then he was off to the next device, a string driver. Within a minute, he had explained what it was (a device for studying wave properties), who made it (James Queen of Philadelphia), and when (about 1890). And then he added, "Oh, by the way . . ."

Scientific instruments--Richard Zitto's collection

Scientific instruments--Richard Zitto's collection

Richard Zitto is seen holding a rare two-cylinder vacuum pump from the 1850s, made by the Benjamin Pike Company, which produced physics apparatus in New York City. Zitto is in talks with the Smithsonian Institution to possibly put the antique vacuum pump in the national museum’s collection.

A collector, Richard Zitto, of scientific apparatus will now offer items to the Smithsonian Institute. Many instruments are rare and exhibit a craftsman's skills and a sense of aesthetics.

Retired physics instructor Richard Zitto stores much of his antique physics apparatus collection in a two-story barn, in a cozy home office with an Albert Einstein action figure on the wall, and in a garage so cramped and cluttered it's hard to walk through.

Inside that garage last week, Zitto lifted up something that, to untrained eyes, resembles a dusty hunk of junk. It's actually a rare vacuum pump - in working condition - that dates from before the Civil War.

And it soon may be on display at the Smithsonian Institute in Washington, D.C.

Zitto will meet with representatives of the national museum in October so Smithsonian officials can decide if they would like to include in their collection two of Zitto's antiques - one is the two-cylinder vacuum pump, the other an electro-static generator, both made in the 1850s by the Benjamin Pike Company.

Zitto hopes the Smithsonian might to take more than just the two pieces from his large collection of vacuums, voltmeters, amp meters, sonometers, and other physics demonstration equipment. If the collection gets passed down a generation, his two grown daughters certainly won't know what to do with it.

"Our kids tell us that he better have directions for taking care of it when he croaks - when he passes away - because they'll have no idea what to do with it," said Zitto's wife, Pam.

Zitto began amassing his large collection of physics-related antiques in 1969, he said, just one year after he began his first teaching job, at Kenton Junior High School, in Kenton, Ohio. A new high school had been built and the district purchased all new physics equipment.

"I just started just to salvage stuff," Zitto said. "I was afraid it was going to be thrown away. Some of the instruments were really beautiful. I didn't want to see them trashed."

The antiques, often very sturdy and with detailed brass and woodwork, are simply better than new physics teaching instruments, Zitto said. New instruments may be more precise, but only slightly. The old ones get the job done just as well.

Zitto later taught physics at Boardman High School from 1976 to 1999 and at Youngstown State University from 1981 until December 2007. His classes often utilized the antiques in his collection.

In 1978, Zitto, along with six other local physics teachers, founded the Physics Olympics at YSU. At its zenith, 32 area high schools schools participated, competing in areas such as the mousetrap racer, the egg drop and the bridge break, Zitto said. He has been involved every year since its beginnings, he said.

Zitto also helped start the Youngstown Area Physics Alliance, for which he served as co-director for 18 years.

In July, The American Association of Physics Teachers awarded Zitto a Distinguished Service Citation at its summer meeting in Edmonton, Alberta, Canada.

He also keeps busy by serving on Columbiana's parks and cemetery and library boards. He's been on the library board for 20 years and helped steward the building and later additions to the library.

He's also working to turn his barn into a museum space for his collection.

"I'm a do it yourselfer," Zitto said. "If something needs fixed, I'll fix it - or I'll try."

That credo also applies to his physics antiques. All of the instruments are in working order, or will be, once he gets the chance to fix them.

"Most people in physics are a little different," Zitto said. "They have a little different flair."
