You don’t often see a brass sidewalk plate placed by a plumbing firm, but the block of Clay Street between 14th and 15th Street was a prestigious address: the new H. C. Capwell store, built between 1910 and 1912 right behind the site of the new City Hall. There are more of these on the 14th Street side.
William S. Snook was a prominent Oaklander in his time, as recorded in Oakwiki. The 1911 directory lists his eldest son Frederick as a plumber, so we can assume that Frederick was the “Son” of the firm. The elder Snook died that same year.
There may be older Snook plates extant, which would read “W. S. Snook & Sons.”
