Andrew H. Bobeck came to Purdue as a member of the Navy's V12 Program. Following his discharge from the Navy, he returned to complete his BSEE in 1948 and his MSEE degree in 1949. After graduation, Bobeck joined Bell Telephone Laboratories where he specialized in the development of magnetic components. His early work included the design of the first solid-state driven core memory and the invention of the twister memory. Later in his career, he studied distributed feedback lasers use in gigabit per second communication systems.

Bobeck is co-inventor and sole author of the first technical paper on the magnetic bubble concept and holds more than 120 U. S. patents. One of his most significant contributions was the discovery that garnet materials can be prepared with growth-induced uniaxial anisotrophy, a process that produces the epitaxial garnet films in general use today.

Bobeck is an IEEE Fellow, has served as a Distinguished Speaker for the IEEE Magnetics Society. He also is a member of the National Academy of Engineering. He has received the Stuart Ballantine Medal from the Franklin Institute, the Electronics Magazine Annual Technology Achievement Award, the AIP Prize for the Industrial Applications of Physics, and the Valdemar Poulsen Gold Medal from the Danish Academy of Technical Sciences. He received the Thomas Alva Edison Patent Award in 1981 and the 1987 Achievement Award from the Magnetic Society. He was co-recipient of the 1975 IEEE Morris Liebman Award.

Purdue honored Bobeck as a Distinguished Engineering Alumnus in 1968 and awarded him an honorary doctorate in 1972.
