Biographical Sketch: I have been working with IMS in one way or another since 1970. I studied it as a student, taught it at a university, joined IBM and supported it in the field, taught the full IMS curriculum in IBM Education, moved to SVL and did technical planning for it, did strategic planning for it, supported it in Level 3, got laid off and joined BMC where I work on MainView for IMS. After 40 years I am still fascinated by IMS.
