William Leonard Pereira (April 25, 1909 – November 13, 1985) was an American architect from Chicago, Illinois, who was noted for his futuristic designs of landmark buildings such as the Transamerica Pyramid in San Francisco. Remarkably prolific, he worked out of Los Angeles, and was known for his love of science fiction and expensive cars, but mostly for his unmistakable style of architecture, which helped define the look of mid-20th century America. Personal life Pereira was born in Chicago, Illinois, the son of Sarah (Friedberg) and Saul Pereira. His paternal grandfather was of Portuguese Sephardi Jewish ancestry, and his other grandparents were Ashkenazi Jews. Pereira graduated from the School of Architecture, University of Illinois and began his career in his home city. He had some of his earliest architectural experience helping to draft the master plan for the 1933 "A Century of Progress" Chicago World's Fair. With his brother, Hal Pereira, he designed the Esquire Theater at 58 East Oak Street, considered one of Chicago's best examples of Art Deco style. He had two wives, former model and actress Margaret McConnell (1910-2011, married June 24, 1934) and Bronya Galef; the latter marriage ending with his death. He has a son, William Pereira, Jr., and a daughter, Monica Pereira, a Spanish teacher. In stark contrast to his famous modernist design sensibilities, Bill Pereira once practiced out of a small collection of rustic looking offices on the site of what was then known as the ‘Buffalo Ranch,’ part of the much larger Irvine Ranch, two miles from where the UCI campus stands today, in Corona Del Mar/Newport Beach. He chose to live in the beautiful Emerald Bay community in north Laguna Beach, and in later life always considered Laguna as his home town. William Pereira died of cancer at age 76 at Cedars-Sinai Medical Center in Los Angeles. At his request, no funeral services were planned. Career Pereira moved to Los Angeles in 1933, and Hal also relocated there in that decade. After working as a solo architect, Pereira was hired by the Motion Picture Relief Fund and designed the first buildings for the Motion Picture Country House in Woodland Hills, California, which was dedicated September 27, 1942. Pereira also had a brief stint as a Hollywood art director. He shared an Academy Award for Best Special Effects for the action/adventure film Reap the Wild Wind (1942). He was the art director
