During the 1960s, before court-mandated busing was instituted, Sunnyside was one of two schools where students from the Bayview were bused to, in order to relieve congestion at the overcrowded Bret Harte Elementary School. That meant a greater diversity of kids at Sunnyside, even before the official busing program began in 1973. And it shows in these two sets of photos, from the late-1940s and the mid-1960s.*
I am grateful for the spontaneous contributions of one-time Sunnyside students Anthony Eckstein and Alan Hansen.
*My thanks to Marty Hackett, who brought this interesting fact to my attention, which was subsequently borne out by my research into the SFUSD papers concerning the program that are archived at the San Francisco History Center.
