(69406) Martz-Kohl Inner Main-belt Asteroid
Discovered on 30 September 1995 by C. W. Hergenrother at Catalina Station.
The name honors the founders and volunteers at the Martz-Kohl Observatory (Frewsburg, NY), whose mission informs, educates and inspires the general public and supports teaching of astronomy. In 1958, Marshal Martz hand-built one of the largest-ever amateur telescopes and dome, later expanded by Ron Kohl’s gift of his telescope and dome.Naming citation (WGSBN Bull. 1, #12, 8), IAU / Minor Planet Center, via NASA/JPL
