Andrew V. Haeff (A'34-M'40-SM'43-F'49) was born in Moscow, Russia, on December 30, 1904. In 1928, he received the degree of Electrical and Mechanical Engineer from the Russian Polytechnic Institute at Harbin, China. In 1928 he majored in electrical engineering at the California Institute of Technology, where he obtained the M.S. degree in 1929 and the Ph.D. degree in 1932.

As a special Research Fellow at the California Institute of Technology in 1933, Or. Haeff studied methods of generation of microwaves, and invented the deflection type traveling-wave tube. From 1934 to 1941 he was with the Research Laboratories of the Radio Corporation of America, where he contributed to the study of ultra-high-frequency phenomena and space-charge effects in electron tubes, and invented the inductive output tube and other ultra-high-frequency tubes and circuits.

In 1941, Dr. Haeff joined the staff of the Naval Research Laboratory as Consultant in Electronics, where he contributed to the early studies of radar systems, was responsible for the development of wide-band ultra-high-frequency signal generators, and took part in radar countermeasure activities.

After the War, he organized the N.R.L. Vacuum Tube Research Branch, directed its work, and contributed by original inventions which included the memory tube and the electron wave amplifier.

In 1950, Dr. Haeff joined Hughes Research and Development Laboratories where he organized the Electron Tube Laboratory, which under his direction is presently engaged in research on microwave and storage tubes. Dr. Haeff was the first recipient of the Harry Diamond Memorial Award for "his contributions to the study of interaction of electrons and radiation, and for his contribution to the storage tube art."
