James Monroe Hewlett

James Monroe Hewlett (1868–1941), American architect and mural painter, father of Anne Hewlett and thus Buckminster Fuller's father-in-law — and the inventor whose building-block patent gave Fuller his first business.

Hewlett was an established New York architect and muralist. His patented method of construction using compressed fibrous ("excelsior") blocks became the Stockade Building System, which he and Fuller developed into a company in the early 1920s. Running that venture was Fuller's first sustained business enterprise; it built scores of houses before Fuller was pushed out around 1927 (following the firm's acquisition by the Celotex Corporation).

Relationship to Fuller

Relationship: family (father-in-law). Hewlett is Anne Hewlett Fuller's father and R. Buckminster Fuller's father-in-law. The tie is both familial and formative: through Hewlett's patent and partnership, Fuller entered the building industry with the Stockade Building System — the venture whose collapse fed directly into the 1927 crisis and turnaround that reset Fuller's life. Hewlett connects Fuller to architecture and to the family into which he married in 1917.
