Leo and his beloved wife Claire shared 65 years of marriage, 62 of which were spent in West Roxbury, where they built and nurtured their family. The couple faithfully and enthusiastically supported their children’s activities, from marching band events and concert recitals to soccer games and long distance road races. Following their retirements, the couple traveled extensively in the United States and Europe. For many years the coast of Maine was a favorite vacation destination.
A lifelong reader, Leo always had a book close at hand. He had a particular interest in the history of Europe and the Arab world, as well as the field of communications.
