[1] Founded in 1925[2] and known by various names through the years, the firm is responsible for the design of several major Chicago landmarks including Water Tower Place in 1975 and Two Prudential Plaza in 1990.

The firm was founded by Armour Institute of Technology students Jerrold Loebl (1899-1978)[3] and Norman J. Schlossman (1901-1990)[4] in 1925, initially focusing on housing design.

The firm designed the Stein residence[8] and the Frederick Penfield house[9] in 1926 and 1927 respectively, both in the French Revival style and considered 'Historically Significant' by Glencoe Village.

The town's innovative 1949 Park Forest Plaza shopping center developed into another sideline for the firm: a genre of rambling, cleverly landscaped, village-like outdoor malls.

Bennett left in 1974 to teach at the Harvard Graduate School of Design; Dart's career hadn't peaked when he died of an aneurysm in July 1975.
