Michael Joseph Callahan

I also worked with Mike at MMI. He was one of the true "good" guys and a strong leader. He loved his kids, Nina and St. Paddy's Day. My deepest condolences and best wishes to his Family!

Kevin, Laura and Brian, I'm so sorry to hear of your father's passing. He was a marvelous man. My thoughts are with you guys.

A real gentleman, an excellent engineer and truly a good friend.

We have many wonderful memories of Mike and Nina from our Motorola years.
With love to his family, Brent and Jeniel Dickson

We are deeply saddened to learn of Mike's passing. I always held him in the highest admiration and respect, starting even from when I was just his little cousin, and on throughout his remarkable life of achievement. I also want to “chime in” on behalf of my deceased parents, and share with Mike's family the understanding that my Mom and Dad (an MIT grad himself), were so immensely proud of and loved Mike, almost to the point of considering him to be another son. Indeed, the whole world owes...

WORKED WITH MIKE FOR YEARS, A GREAT PERSON,MY PRAYERS ARE WITH THE FAMILY.

May God bless you and your family in this time of sorrow.

Cousin Mickey was a great man. Remember him visiting Wallingford ct Wiltons when I was about 8 years old. Miss him and his mom Francis.

Mike and Nina were among our first and best friends at Motorola. Our kids and their kids grew up together, and we have many great memories of them all. Mike was handsome, funny, loyal and smart. We went to see Dr. Strangelove with them, and had many political debates after that movie. Our deepest sympathies go out to the Callahan family--your father will be deeply missed and never forgotten. Lovingly, Otis and Judy Wolkins

Thoughts of love and support for Kevin. Laura, Brian and the grandchildren. My dad, Mike's first cousin and I visited him just a couple years ago. I was lucky enough to have Mike as a guest at my wedding in 2002.
