As the Olmsteds balanced hundreds of projects in the 1920s, they had to stay in constant communication with their clients and off-site employees. Stenographers, secretaries, typists, and telephone operators all helped the firm stay up-to-date. If the partners wanted to write a letter, they often dictated to a stenographer who worked in these cubicle-like areas referred to as coops. Olmsted Brothers also bought a machine called the ediphone to help them. The ediphone was an early recording device that someone could record on and later re-play.
A majority of typists and stenographers in American offices were younger women, and this was most likely the case with the Olmsteds as well. At the time, many people assumed that younger women would not stay employed for very long as they would be biding time until they got married.
