Theater. Modernism. (Simonson, Lee). PART OF A LIFETIME by Lee Simonson. Duell, Sloan & Pearce, NY, 1943. Obl. 4to., cloth, DJ, 100pp. text and 80 plates in color and b/w. Fine, DJ has a few nicks and small tears. Lee Simonson, who spent his youthful years in Paris deeply immersed in the milieu of the Synchromists, Stein & Toklas, the Ballet Russe, etc., returned home to become one of America's pre-eminent stage designers. This memoir covers these early years and also his theater work, the plates being primarily illustrations of his theater sets.
