(Although little apparently was done with his idea, Schnitzer's thinking, along with similar thoughts by many of his colleagues, created a fertile environment within NASA for the idea of adapting Apollo-developed space hardware to laboratories and space stations in Earth orbit.) In April 1962 Paul Hill, Chief of the Applied Materials and Physics Division, stated that structures were under study which could hold from 4 to 30 people.
