The UCD Department of Special Collections website includes a selection of “Historic Picnic Day Films,” one of which is reported to be “the oldest known footage of campus,” here: https://www.library.ucdavis.edu/dept/specol/collections/media/?media=picnicday
That footage is dated April 22, 1939 (screenshot below).
“Est” declarations, such as “oldest,” tallest,” “fastest,” “best,” and the like, are implicit challenges and, I suppose, even part of human DNA. Once issued, an “est” challenge sets a benchmark for evaluating future events of that type.
So, when I came onto a film made on the UCD campus on April 21, 1930, one of my thoughts was “this might be the oldest UCD campus film!” In that spirit, I call attention to it on Davis History Today.*
