Thomas (Tom) M. Whitney

Leader of the team that invented the HP-35, the world's first handheld scientific electronic calculator, Whitney was also an early employee of Apple Computer. Thomas (Tom) M. Whitney graduated from Aurelia High School in Aurelia, Iowa in 1957. He completed his B.S. degree in 1961, his M.S. degree in 1962, and received his PhD in 1964, all in Electrical Engineering at Iowa State University, where he was a member of Acacia fraternity.

Whitney joined Hewlett-Packard in 1967, where he led a team of engineers that invented the HP-35. Named for its 35 buttons, the HP-35 was the first pocket calculator able to perform trigonometric functions. Before the HP-35, handheld calculators were only capable of addition, subtraction, multiplication, and division. During his years at HP, he also served as a lecturer at Santa Clara University.

In 1978, Whitney joined Steve Jobs and Steve Wozniak as one of the earliest employees (#15) of Apple Computer. He served as the Executive Vice President for Engineering, working alongside Jobs and Jef Raskin. He helped to develop the Apple II, the world's first accessible and highly successful personal computer. After his Apple years, he became an entrepreneur himself in 1981, launching several companies in Silicon Valley, California.

Whitney was a recipient of the Outstanding Young Alumnus Award from the ISU Alumni Association, as well as a recipient of the Professional Achievement Citation from the Iowa State University College of Engineering. He passed away in 1986 at the age of 47. His wife, Donna, became active with Iowa State after her husband's death. She established the Thomas M. Whitney Professorship of Electrical and Computer Engineering, a program that supports Iowa State University's Department of Electrical and Computer Engineering's research, prominently in regards to nondestructive evaluation and solar energy research.
