Wallace Neff (January 28, 1895 – June 8, 1982) was an architect based in Southern California and was largely responsible for developing the region's distinct architectural style referred to as "California" style.
Neff was a student of architect Ralph Adams Cram and drew heavily from the architectural styles of both Spain and the Mediterranean as a whole, gaining extensive recognition from the number of celebrity commissions, notably Pickfair, the mansion belonging originally to Mary Pickford and Douglas Fairbanks.
