Description & Details

The Antique Scientific and Technical Instruments auction at Gray’s on September 9 features 246 lots of highly collectible instruments, a large collection of which is being sold to benefit the Case Western Reserve University’s Dayton Miller Scholarship Fund. The catalogue and live online bidding are now available at GraysAuctioneers.com.

Highlights include a dazzling array of instruments from two prestigious Ohio collections. Lot 1 is a Tesla Coil, one of 40 built by G.B. Schneeberger. This Tesla coil is said to deliver an entertaining 40 inch electrical streamer. Lot 4 is a Holtz-Toepler Electrostatic Generator built by Central Scientific of Chicago late 19th/early 20th century. It was used in early X-ray photography.

Lot 16 is a Quadrant Electrometer an early instrument which measures electrical charge. Lot 72 is a Wheatstone Bridge used in the late 19th century used to measure unknown electrical resistance.

There are several lots pertaining to early electronic communications including lot 95 a Telegraph Pen Register with Tape Roll. By the end of the 19th century, pen registers were widely used to record pulsed electrical signals, eventually being used to record the phone numbers dialed from a particular location. Today sophisticated pen registers are used for surveillance purposes.

The auction features a large collection of telescopes, microscopes and spectroscopes including Lot 121, a large spectroscope used to measure the properties of light over a specific portion of the electromagnetic spectrum. 

While all of the lots in the auction have historical significance for the dedicated collector more casual collectors will be intrigued by the design and decorative aspects of the collection. The proceeds will benefit the Dayton Miller Scholarship Fund named in honor of Dayton Clarence Miller the discoverer of ether drift, and will provide scholarship funds to students in the Physics Department at Case Western Reserve University.

Live preview for the auction is from September 3 - 8 from 9 – 5pm at Gray’s auction showrooms in Cleveland. The auction house will be closed September 6 & 7 for the Labor Day holiday. The auction on September 9 starts at 11am; telephone, absentee and live online bidding are available.
