12142 Franklow           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld at Leiden on Palomar Schmidt plates taken by T. Gehrels.
American physicist Frank J. Low (b. 1933) invented the gallium-doped germanium bolometer and became a leader in infrared astronomy. He pioneered open-port airborne astronomy and helped develop infrared spaceborne astronomy.
