San Francisco Block Books - 1935 & 1946

This was an unexpected find that I came across recently. I was looking up addresses and property information for San Francisco to see what I could find and came across old San Francisco Block Books from 1935 and 1946 on the San Francisco County Assessor's website:

These old Block Books from 1935 & 1946 are available by clocking on the Access Tool, typing in a property address and then looking under the official maps that are available. The first address I looked for was 59 Collins Street, where Frances and her husband David Nemetzky lived. At first, I wasn't finding anything, but after a chance search for the home on google maps (I have some pics of the home from the 1930's - I will post these below), I found the correct address. The address is now 169 Collins Street and appears to have been changed during the 1950's. I found the Block Books from both 1935 and 1946 which are below:

1946 Block Book - 59 Collins Street

According to the San Francisco Assessor's website, the house was built in 1914. Frances and her husband Thomas Fogalsang purchased the home in 1918. Frances lived there until 1946, when she and her second husband, David Nemetzky, moved to 1234 39th Avenue. Frances lived there until the early 1950's. Below are pictures from Google Maps Street View of the homes on Collins Street and 39th Avenue.

The 1935 Block Book also helped answer a question I had about the house Thomas Fogalsang owned at 155 Vienna Street, which was built in 1900. At the time of his death in 1928, the house was occupied by Bertha Fogelsang (possibly his previous wife/common law wife/business partner), but was in his name. Before I go any further, Bertha changed the spelling of Fogalsang to Fogelsang to possibly distance herself from him (the reasons aren't known, but possibly due to his marriage to Frances in 1916). According to the 1935 Block Book, the house at 155 Vienna Street was in Frances' name. Below is the 1935 Block Book.

One note about this property - while her residence at 59 Collins Street is listed under Frances Fogalsang, the home at 155 Vienna Street is listed under Frances Nemetzky. After Bertha's death in 1934, Frances sold this property.

The other Block Books I found were for Clarence Keith Newitt. He was living with his wife Mary at 245 Cotter Street in 1935. Below is the 1935 Block Book for Keith & Mary Newitt.

This house was built in 1912. Keith and Mary lived here until 1936, when they moved to 43 Cotter Street (built in 1910). Below are google images for both 245 Cotter Street and 43 Cotter Street.

By 1944, Keith and Mary had moved to 2965 24th Avenue (built in 1936). Mary passed away in May of 1944, and Keith remarried in November of the same year. He and his second wife, Arlene Christensen, are listed in the 1946 Block Book, which is below, along with an image of their home from google.

Below are pictures of the home at 59 Collins Street from 1936, when my grandpa and his family visited Frances and David in San Francisco. While there are a few differences in the home, such as the front door (wood vs. glass) for example, the façade of the home is the same. Even the window design has been kept the same over the years. Take a look and compare. I'm glad to see the front of the house has largely remain unchanged over the years.
