Keyes, Lethbridge & Condon

Keyes, Lethbridge & Condon was an American architectural firm active, under several different names, in Washington, D.C. from 1951 to 1997.

The increase in new projects led to significant growth, and in 1985 four new partners, Thomas Eichbaum, Philip Esocoff and David King, were added.

Florance, Eichbaum, Esocoff and King adopted a more pluralistic approach to design than the founders, and embraced postmodernism and other contemporary trends.

[2] In 1995 Esocoff withdrew from the partnership, and the firm returned to its former name of Keyes Condon Florance.

[7] Francis Donald Lethbridge FAIA (October 5, 1920 – April 17, 2008) was born in Hackensack, New Jersey.

[8][9] As chair of the federal Joint Committee on Landmarks of the National Capital, Lethbridge helped establish the District of Columbia Inventory of Historic Sites.

[11] Colden l'Hommedieu Ruggles "Coke" Florance FAIA (January 24, 1931 – December 28, 2023) was born in Baltimore.

He served in the navy until 1959, when he joined Satterlee & Smith before moving to Keyes, Lethbridge & Condon in 1961.

[12] He left in 1968 to form the partnership of Florance & Cohalan, and later managed a solo practice before returning to Keyes, Lethbridge & Condon.

[13][14] Florance was married three times: to Barbara Dale Crosby, Elizabeth Owens and Nancy Griscom.

[15] Like Berla & Abel before them, Keyes, Lethbridge & Condon and its successors were noted as an incubator for young architects.

Other employees who established successful local and regional practices include Heather Cass of Cass & Associates, Winthrop W. Faulkner, William C. Gridley of Bowie Gridley Architects and Jack McCartney and Anne McCutcheon Lewis of McCartney Lewis Architects.
