Found photograph. Among the mementos collected during his life, mycologist Bernard Lowy had a photograph from Barro Colorado Island dated July 1950. It shows A. M. Chickering (leading), a tropical spider specialist, and James Zetek, the "Baron of BCI," descending the steep grade to the dock depicted in one of our photographs. Our photograph of the 196 steps (looking up) was taken almost exactly 51 years later (see lower part of page 4). Another interesting comparison is the change in island dress over the intervening 51 years. The black and white photograph by an unknown photographer was discovered by chance after ours had already been posted.
[A note in September 2001 from Allen Brady, Hope College, Holland Michigan, who knew him tells about Dr. Arthur M. Chickering. He was chair of the Biology Department at Albion College in Albion, Michigan, for more than 30 years. He had completed his degree at Yale University under Alexander Petrunkevitch, another famous arachnologist. Chickering first visited Baro Colorado Island in 1934 and made subsequent trips in 1936 and 1939. He continued working with Panamanian spiders for many years. The last publication I [Allen Brady] have from him is dated 1972, a paper on "The genus Oonops (Araneae, Oonopidae) in Panama and the West Indies (Part 3)." His most notable work was a monograph on the Salticidae of Panama (1946) consisting of 474 pages in which he described 172 species.]
