Courtesy photo This photo goes back to 1965, when Nashua native and longtime U.S. Postal Service official Dennis J. Sullivan won his first of several terms as Nashua mayor. Sullivan, who resigned from office in 1977 due to health reasons and died in 1978, is in the front row, third from left in this photo; his wife, Claire, is seated to his left. Although Sullivan was controversial at times, due in large part to his fiscal conservatism that critics said kept Nashua from moving forward on a variety of fronts, voters continued reelecting him through the 1960s up until his 1977 resignation. It's not clear if the people in the photo are city officials who supported him, or were members of his successful campaign.
