Architects Whidden & Lewis thought enough of the Wilcox to move
their business offices into it after construction was complete. They also thought enough of the building's design to do an encore presentation with the nearly identical Stevens Building (1914, a.k.a. the Standard and Farwest Assurance, 812-820 Washington Street). Both buildings were designed by Whidden and Lewis in a modern style and built to the same height. Both are steel-framed office structures with white terra-cotta sheathing on the upper floors and ample windows.
Theodore Burney Wilcox (1856-1918) was born in the thriving metropolis of Agawam, Massachusetts. While working in a bank, he impressed a visiting Portland banker enough for him to offer Wilcox a job in Portland. The move worked out well for Wilcox; when he died he was worth in excess of $10,000,000. (He didn't leave a penny to charity.) Wilcox financed both the Wilcox and the Stevens Building.
