Oscar Gregory Stonorov (December 2, 1905 – May 9, 1970), was a modernist architect and architectural writer, historian and archivist who emigrated to the United States from Germany in 1929. His first name is often spelled "Oskar".
Stonorov was born in Frankfurt, Germany, and studied at the University of Florence (1924/25), Italy and at the University of Zurich (1925–1928), Switzerland, and apprenticed with French sculptor Aristide Maillol. In 1928, he worked in the offices of André Lurçat in Paris, France.
In 1940 Stonorov, along with George Howe, worked on the design of housing developments in Pennsylvania with Louis Kahn. A formal architectural office partnership between Stonorov and Louis Kahn began in February 1942 and ended in March 1947, produced fifty-four known projects and structures.  In 1943, Stonorov co-wrote with Kahn Why City Planning Is Your Responsibility and in 1944 again collaborated with Kahn to write You and Your Neighborhood ... A Primer for Neighborhood Planning. Between 1950 and 1954 Philadelphia architect and future Pritzker Prize winner Robert Venturi (who later worked directly for Kahn) worked in the offices of Stonorov. In 1957 he established the partnership of Stonorov & Haws.
Stonorov lived and worked near Philadelphia, where he designed modernist public housing, such as the Carl Mackley Houses, which was added to the Philadelphia Register of Historic Places in 1982 and the National Park Service's National Register of Historic Places in 1998. Because Stonorov was not registered as an architect in the United States at the time, William Pope Barney was enlisted as chief architect for the purposes of obtaining permits from the city.
Stonorov dedicated a significant amount of his life to researching and compiling the archives of Swiss architect Le Corbusier and co-edited, with Willy Boesiger and Max Bill, the Œuvre complète: Le Corbusier et Pierre Jeanneret, the definitive 8 volume set of the complete work of Swiss architect Le Corbusier initially released between 1929 and 1969 as a result of Stonorov and Boesiger working directly with Le Corbusier.
Stonorov died with Walter P. Reuther, president of the United Automobile Workers, when Reuther's Gates Learjet 23 crashed on approach to Emmet County Airport (now Pellston Regional Airport) in Pellston, Michigan. Also killed were Reuther's wife, his bodyguard, and the plane's pilot and copilot. Reuther and Stonorov were to have performed the final inspection of a union recreation and education facility Stonorov had designed at Black Lake, Michigan 25 miles (40 km) from Pellston. The center was to open three weeks after the crash.
With his wife, Elizabeth Foster "Miss Betty" Stonorov (March 5, 1906 - December 8, 2003), Stonorov had daughters Katrina Daly, Tasha Stonorov Churchill and Andrea Stonorov Foster as well as a son Derek Stonorov and nine grandchildren. They lived at Avon Lea Farm in Charlestown Township, outside Philadelphia.
