  • Occupation:
    Xerox Corp. | Vice President of the Systems Group

    When John B. Cahill was an undergraduate at Boston College, he was a real good-time guy, and his friends nicknamed him Mad Dog. But he calmed down and matured into a gregarious family man with a quirky sense of humor.

    Mr. Cahill, 56, lived with his wife, Sharon, and two sons, Brett, 17, and Sean, 15, in Wellesley, Mass., and worked as a vice president of the systems group at Xerox . But he planned to retire at the end of the year to start his own consulting business. The name of it was MDI. His family knew what the initials stood for: Mad Dog Industries.

    On Sept. 11, he was on Flight 175 to Los Angeles, where he was going to visit a friend and do some work on the new business. He had a passion for travel; the family had lived in England and Brazil. He was fond of Latin America, and planned to make it a focus of MDI. "He loved the people," Mrs. Cahill said. "They work to live instead of living to work."

    Mr. Cahill spoke Spanish and Portuguese, and his interest in languages was picked up by his children. Brett is taking three languages — French, Spanish and German. "He got that from John," Mrs. Cahill said, "who realized the world was smaller than it seems."

    We both attended the Memorial service for Joe. Lian was only 7.5 at the time but she knew very well that her cousin Joe was a very special person. I am 9 years older than Joe and his Dad and my Dad were brothers. I still miss his signature smile his sense of humor and his larger than life person! I know that God brought a very special person home to be with HIM and the communion of saints on 9/11/01 and I further know that Joe was with my Dad and Mom, his Dad, our grandparents, Leonore , Nonnie and Poppie Schwarz and Grandmom Fontanella when Janet was welcomed to heaven in 2007. May his soul together with all the souls of the faithfully departed through the mercy of our loving God rest in peace. AMEN. Posted by Lian and Tom Lenihan
