"From a safe distance in a cherry tree, the two boys observed events around Behrens's studio, accommodated in a garden house. As Eiermann recalled, they often watched coworkers Gropius and Le Corbusier head off for lunch together; on one occasion, childish mischievousness even prompted the boys to bombard Mies van der Rohe with cherry pits. Once the office had shut down for the day, the two pals would invade the unlocked studio to stand together in awestruck admiration before drawings of the Petersburg embassy lying on the worktables."
