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 two years later, he became a computer programmer at the IBM Poughkeepsie Programming Center, where he worked on the OS/360 OS. Rogers continued to work on mainframe OS 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. More recently, 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. He has been a popular and frequent speaker at SHARE for many years.
