In January of 1995 I was a member of the board of the Amateur Computer Group of New Jersey (ACGNJ) one if the first such groups formed. The other board members tired of my constant prodding to get onto the Internet and I was appointed to form an Internet Special Interest Group (SIG) for the club. I ran this group from 1995 to 2001 when the Internet had become so widespread that it permeated almost all the computer arts and we dissolved the group.

In 1990 I began to work during the spring as a volunteer with the American Association of Retired Persons (AARP) program: Tax Consultants for the Elderly (TCE). I worked in the Essex County, NJ chapter assisting seniors in the preparation of their US tax returns. About ten years later the IRS made tax software a part of the program and as I was one of the few counselors with computer knowledge, it fell to me to start the program in our county. I was appointed Essex County Technology Coordinator, a post which I held until 2006, when I turned the job over to some of the younger counselors.

I retired from AT&T at the end of 1989. At that time I had been running a small UNIX computing center there, associated mainly with the development of packet networking systems. It was a great privilege to be at Bell during the years when UNIX was exploding and to be working in that general area.

From 1961 to 1975 I was at Brookhaven National Laboratory, where I worked in nuclear instrumentation. I worked on projects for the measurement and analysis of bubble chamber film, developed the first Positron Emission Tomograph (CAT scanner), directed the production of a real-time operating system for the gathering and analysis of spark chamber data at the Alternating Gradient Synchrotron. I participated in the development of control and analysis instumentation for a scanning transmission electron microscope. My work on the bubble chamber film apparatus resulted in a Ford Fellowship to pursue the same type of development at the European Commission for Nuclear Research (C.E.R.N.) near Geneva, where I spent some sixteen months.

From 1953 to 1961 I was a research assistant and later research associate at the Physics Department at Yale University where I worked first on a U. S. Navy radar project and later at the Yale Linear Electron Accelerator Laboratory.

Though I have been interested in computers since the mid '40s, I have been working with computers only since 1950, when I took a position with the Astronomy Department at Yale University. I worked on a project to compute the orbits of the minor planets - the larger asteroids - from measurments made on astronomical plates, using electromechanical IBM punch card computers like the 602A calculating punch. I introduced the utilization of these machines to the Department of Mathematics at Yale for a statistical project, and my mentor, A. J. van Woerkom, introduced them to the Physics Department where they were used to calculate the ground states of the Helium atom. In 1952 I began work on connecting two 602As to avoid many time-consuming sorting operations. Before this was completed, I was transfered to Yale's Statistical Service Bureau. If this work had been completed, it would have been the first multi-processor.

I have a B.A. from Yale, 1950, in Mathematics and Philosophy, an M.A. from Yale, 1951, in Mathematics, an M.S. from S.U.N.Y. Stony Brook, 1975, in Applied Mathematics, and an M.S. from Stevens Institute of Technology, 1981, in Computer Science.
