Kiyo Tomiyasu graduated from Caltech and then obtained an MS in communication engineering from Columbia University and PhD in engineering science and applied physics from Harvard in 1948. He later joined the Sperry Gyroscope Company and in 1955 moved to General Electric, where he worked on microwave and laser projects. He was involved in later years with remote sensing of the earth using a variety of radar technologies. As a result of corporate mergers, he became a management and data systems fellow of Lockheed Martin Corporation in 1995. During his career Tomiyasu was active in the Institute of Electrical and Electronics Engineers (IEEE). He received the organization’s Centennial Medal and its Third Millennium Medal, and was elected an honorary life member of the IEEE Geoscience and Remote Sensing Society in 1999.
