RCA hired Alfred Goldsmith as consulting head of Research Department while he taught electrical engineering at the City College of New York. Two years later, Goldsmith led a crew of engineers, technicians, and scientists to the new Technical and Test Laboratory opposite Van Cortlandt Park in the Bronx in New York City. There they tried to maintain quality control and standardization of the vacuum tubes and radios manufactured by General Electric and Westinghouse Companies and marketed by RCA. Between 1930 and 1932, David Sarnoff re-organized RCA as an independent company that manufactured as well as marketed electronic technologies.
