3950 Yoshida           Discovered 1986 Feb. 8 by S. Inoda and T. Urata at Karasuyama.
Tougo Yoshida (1864-1918), who was born in Echigo (now Niigata prefecture), was a pioneer scholar who over 13 years organized for himself a dictionary of Japanese historical names in geography. He was also interested in astronomy and observed the total solar eclipse in 1887. The name was suggested by K. Hatayama.
