Jack joined my group  as a way to ensure all service tickets generated by the physics group were closed within 21 days so we could meet the Ohio regs limit of 30 days.

His first post was to a rapid response fighter jet squadron during the middle years of the Vietnam war.  Jack was shipped off to the Korean DMZ to work on high power radar on F4 Phantoms just in case North Korea wanted to retake South Korea while we were tied up in Viet Nam.

He rose through the ranks and eventually had the largest service area by population in the USA; it stretched from Boston to Baltamoe and from the Coast all the way to Appalachian mountains. He made a name for himself as trustworthy, fair and efficient.

I came from an academic background at Georgetown U. Jack fit in. Cleveland Clinic was in many ways the Air Force in long white jackets not an ivory tower.

> After Jack and I retired from Cleveland Clinic we decided to go into business together. I joined a local xray consulting group where physicists prepared and completed their own reports. Those who know me know that this was not a strong suit with me. They wanted me and I wanted to work so I asked them if I could hire an administrator. At first they said "no" then "yes" the "can we use him too" !. Together we and I formed PHOTONS Medical Physics LLC and had the time of our lives for the next 10 year. We focused on cone beam dental and traveled to every little cow town in Northern Ohio. We happily tested  these simple little devices, driving, chatting, going out for lunch and a beer after each gig was done. Then at the beginning of the year my sight started to go south and Jack had turned 83. The world was sending me a message it was time to take the win and move on.

> I was with Jack's wife and adult daughter together with my wife when Jack decided that the fight was over. This was 8 hours ago. When Jack passed from this world into the next he was in a place that he loved to work; a Cleveland Clinic Hospital. Jack was taken from the facility on a draped gurney with full military honors. Civilians lined the halls on each side hand over hearts, veterans and active military men and women  stood sharp and hand saluted as he passed.
