5852.165 |
| Note |
Index map to a set of 164 spectacular, large format, sharp, black and white vertical aerial photography partially overlapping images covering San Francisco north of a line approximately between Merced Lake and Candlestick Point. Resolution generally better than one foot and much higher with high contrast features, for example the paint striping on a basketball court. Relative heights frequently discernible based on shadow cast of objects and structures. Handwritten date on index map indicates photographs taken in August, 1938. Owned by the San Francisco Public Library. (Authorship almost certainly incorrectly spelled in handwriting on index sheet as Harrison-Rikker). He married Charlotte Seward in the mid-1920s, after divorcing, he married Esther Miriam Munson in 1936 Aerial Photographer Harrison Clay (Chesley) Ryker (1898-1981) was born in Oakdale, CA. . He served in the U.S. Army for several years in Germany with the post-World War I occupational forces, and partook of educational opportunities at the University of California, Berkeley. Expanding on his hobby in photography, Mr. Ryker teamed with various pilots beginning aerial photography services out of the Oakland Airport and throughout the West. Colleagues included Lage Wernstedt of the U.S. Forest Service. He also worked with the Fairchild Aerial Camera Company (including an aerial survey of Puerto Rico) and Clyde Sunderland of Pacific Aerial Surveys. As well, he took photographs of the devastating 1923 Berkeley Fire, archived in The Bancroft Library. By 1938 Mr. Ryker was listed in business as a map publisher (see Polk's Oakland 1938 Street and Avenue Guide) based at 1924 Franklin St., Oakland. At that time, he had at least one patent pending for a stereoscope used for aerial photograph interpretation. (Note continued in Pub Note field below). |
