Professional History


Founder, Dinwiddie Construction Company, San Francisco, CA, 1911- ; William S. Dinwiddie founded the Dinwiddie Construction Company in the San Francisco Bay Area in 1911. (In the wake of the San Francisco Earthquake of 04/18/1906, abundant construction work was to be had in the Bay Area.) In 1920, he held the title of Dinwiddie Construction's President.

Throughout the course of the twentieth century, it would become one of the largest construction firms on the West Coast, before merging with the E.A. Hathaway and Company construction firm on 10/01/1996.

William and Helen had five sons: Starrett (born c. 1896 in LA), Godwin (also called "Carrington," born c. 1898 in LA), John Ekin (born 10/27/1902 in Chicago, IL), James, (born 01/04/1908 in Berkeley, CA) and Stuart (born c. 09/1915 in OR); four of the five brothers had been born in different states, indicating that the family moved a great deal. It is likely that William S. Dinwiddie's construction projects forced this periodic relocation.



In 04/1910, the Dinwiddie Family lived at 177 Franklin Street, Bloomfield Township, NJ.

Ten years later, it had moved to CA, living at 2943 Avalon Drive, Berkeley, CA; according to the US Census of 1920, the family employed an 19-year-old Irish cook, Grace Dooney at this time.

Like a number of men in his family, William S. Dinwiddie, Sr., died at a relatively young age, 61. He was buried at the Mountain View Cemetery in Oakland, CA.


His parents came from VA.


William S. Dinwiddie married and Helen Starrett Dinwiddie (born 04/14/1872 in Lawrence, KS- d. 08/22/1962 in Contra Costa County, CA) c. 1895. Her parents had come from PA.


Helen and William had five children, all boys: William Starrett Dinwiddie, Jr., (b. 1896 in LA-d. 1928), Goldwin Carrington Dinwiddie (b. 1898 in LA-d. 1957), John Ekin Dinwiddie (b. 10/27/1902 in Chicago, IL-d. 09/11/1959 in New Orleans, LA), James, (born 01/04/1908 in Berkeley, CA-d. 1994) and William Stewart Dinwiddie (born c. 09/1915 in OR-d. 1966).
