After returning from the war, I returned to Queens College to complete my Bachelor of Science degree in Mathematics, which I received in 1947. I became a teacher of high school mathematics in NYC and later on Long Island. I subsequently became an elementary school principal and retired in 1983, after more than 38 years as an educator. I married Sarah Goldberg who was a biology teacher. We had three children, Brian, Gary, and Lynn, and currently have six grandchildren. Two of my proudest accomplishments since my military service are the publishing of a book and earning a doctorate in education. My book, "From Sand Table to Electronic Brain," was published in 1961. It became very popular and was translated into several languages. I earned my doctorate from Nova University in 1975. My wife and I enjoyed traveling throughout the country with our family visiting almost every state and many national parks. I particularly enjoyed participating in nature photography, a skill nurtured by my wife Sarah who was an excellent photographer. I am fully occupied with my interest in all sports, and particularly in watching my grandchildren's participation in sporting events. I am still an active bowler at the age of 80.

Grandpa was an amazing man. He could speak four languages and could play the violin among things. He was born in 1917 and passed away in 1993. During the depression he put himself through college and upon graduation in 1939 he was employed by Eastman Kodak. Except for a short stint at Oak Ridge he worked at Kodak his whole career. He holds 4 patents with Kodak. During the war he worked at Oak Ridge on the gaseous diffusion process. He didn't talk about it much but I'm pretty sure he was part of a team working on the diffusion membrane. I was recently given several mementos of his (including a copy of the same Jan 1945 telephone directory) and was amazed by his accomplishments and honors. I wish I had known all of this while he was alive.

Favorite Story:  I remember getting on "cattle cars" going to work with our shoes in our hands. After we got to the Y-12 plant, we washed our feet and then put our shoes on. All we had was mud, mud everywhere!

My Mother, Bonnie Pauline Hardwick Rogers, was very proud to have worked for shortening the War. She had several brothers in the war and met my father, Eugene Rogers, while working at Y-12. After they married Mom realized that more even more family members were fighting the Great War. Mother often talked of her devotion to shortening the war, whatever it took, to get this awful killing to come to an end. Mom and Dad lost several members of the family to the war and even with that they had no regrets in helping the Manhattan Project. Mom lost a baby while working at Y12 and she often told me how really glad she was to have me, Joy, after her loss.
