# Oliver Rousseau

Oliver Marion Rousseau (1891–1977) was an American architect, home builder/contractor, and real estate developer. He worked in the San Francisco Bay Area, in particular the Sunset District of San Francisco, as well as Hayward, California. He came from a family of noted architects and co-founded the architecture firm Rousseau and Rousseau, and later the Marian Realty Co..

## Early life and family

Oliver Marion Rousseau was born on December 6, 1891, in San Francisco, California. He had six siblings, and their parents were Frances (née Scheibli) and Charles Marion Rousseau (1848–1918). His father, Charles M., was of Belgium ancestry and was born in Rotterdam; he was also an early architect in the city of San Francisco. His two older brothers were Charles John Rousseau (1879–1944) and Arthur Frank Rousseau (1885–1943), were both also architects. The Rousseau family home was located at 1903 Webster Street in San Francisco starting roughly in 1901.
In 1912, Oliver Rousseau married Irene Martha (née Caubu), they had one child; the local newspapers published the couple's separation in 1916. By 1918, they filed for divorce. The Rousseau's divorce was public and "messy", and around the same time his brother Arthur experienced a similar divorce situation.

## Career

Charles M. and his son Arthur Frank collaborated and formed the firm, Rousseau and Son located at 927 Market Street (the Emma Spreckels Building), active from roughly 1901 until 1905. Arthur Frank, then co-founded the architecture firm Rousseau and Rousseau with his brother Oliver, initially located in the same office at 927 Market Street and primarily working in the San Francisco Bay Area. Their father Charles served as the vice president of Rousseau and Rousseau, until his death in 1918. The office for Rousseau and Rousseau moved to 110 Sutter Street, and later to 1141 Market Street in San Francisco in 1923.
In 1922, the two brothers founded the Marian Realty Co. and focused on building hotels, office buildings and apartment houses until the Great Depression. Oliver worked as the architect designing all of the buildings, while Arthur focused on raising money. In 1930, the company pivoted to residential construction and they focused on the Sunset District of San Francisco. The residential houses they designed were often English Tudor Revival, storybook, or Spanish Colonial Revival, and were described as "fairy tale"; these homes are commonly referred to as "Rousseaus". Their designs were a departure from the cookie-cutter homes prevalent in the Sunset District at the time.
In 1933, Marian Realty Co. declared bankruptcy. Oliver separated from his family business at that point and went on to work as a architect on a development in the East Bay, primarily tract homes and apartment buildings. He also remarried.
Rousseau died on May 30, 1977, in San Francisco, California. Herb Caen wrote, upon his death, "Another Memorial Day death: Oliver Rousseau, who built good houses while all about him, the pure schlock was rising."
