David Peck Todd

Obituary: PASP 51, 247 (1939)

In the NGC Todd is listed eight times as discoverer: NGC 3134, 3217, 3279, 3436, 3685, 3849, 4202 (here "Tod" is a typo) and 4355. In 1877-78 he used the 26" f/15 Clark refractor of the U.S. Naval Observatory, Washington D.C., to search visually for the trans-Neptunian planet. A careful investigation of his paper - Todd, D. P, Telescopic search for the Trans-Neptunian planet, AN [2698] 113, 153-160 (1885) - showing over 30 nebulous objects, leeds to the following result: Todd found 20 NGC-objects (9 were new) and discovered 3 IC-objects; all are galaxies in Leo or Virgo.
