In this oral history, Dr. D’Asaro describes his upbringing in a small town in the Midwest during the Depression. After spending time in the Navy, he earned a MS in Physics from Northwestern and a PhD from Cornell in 1955. He then went to work at Bell Labs. The oral history traces his many contributions to the area of solid state electronics, including work on an early integrated circuit, stepping transistors, light emitting diodes, gallium arsenide, and solid state lasers. Arthur could have been credited with the invention of the integrated circuit if he had further pursued some of his early research. In addition to his description of his technical research accomplishments, he spoke about the strengths and weaknesses of Bell Labs and its approach to research. He finished his career at Princeton Optronics.
