Bob Rogers worked on mainframe system software for 43 years at IBM before retiring as a Distinguished Engineer in 2012. He started with IBM as a computer operator in 1969. After receiving a B.A. in Mathematics from Marist College in 1971, he became a computer programmer at the Poughkeepsie Programming Center, where he worked on the OS/370 operating system. Bob continued to work on mainframe operating system development for his entire career at IBM. He contributed to the transitions to XA-370 and ESA/370, and was lead software designer for the transition to the 64-bit z/Architecture. He implemented the support for single z/OS images with more than 16 CPUs and was a lead designer of the z/OS support for the zAAP and zIIP specialty engines. Today's z/OS implements dozens of his design ideas. Bob has been for many years, and continues to be, a popular speaker at the IBM System z technical conferences and other venues. He is currently working with Trident Services, a California-based z/OS software and services company. Bob has also returned to IBM as a part-time retiree supplemental on the zVM development team.
