Francis B. "Fran" Nimick, Jr. had ties to Dollar Bank from the day he was born. His father, steel company manager Francis B. Nimick, Sr., opened a Dollar Bank savings account in trust for his infant son when the latter was just four days old. Francis B. Nimick, Sr. was a Dollar Bank trustee, as had been his father, Frank B. Nimick. The Nimicks were an old Pittsburgh family with roots in the early days of iron and steel manufacturing. Francis B. Nimick, Sr. and his wife, Mary Spencer Nimick, lived with their five sons and daughter on Thorn Run Road in Coraopolis Heights.
Fran Nimick attended Philips Exeter Academy, then graduated from Princeton University in 1939 and Harvard Business School in 1941. He held his first post-graduate job at Peoples First National Bank & Trust Co. only a short time before the United States entered WWII. Nimick served as a warrant officer in the U.S. Army from 1942-1946. After the war, he returned to his job at Peoples First National Bank & Trust Co., until he was offered the position of assistant treasurer at Dollar Bank in 1952. It was the second, and last, company he would ever work for.
Fran Nimick rose to treasurer and vice president. When he became president of Dollar Bank on January 1, 1959, he was just four months shy of his forty-first birthday, making him the youngest bank president in Allegheny County. Nimick oversaw the development of branch banking at Dollar Bank, driven by real-time, networked teller accounting machines. By December 1978, Dollar Bank had 21 locations in four counties.
For 73 years, Fran Nimick served the congregation of Sewickley Presbyterian Church. He was on the boards of Chatham College, Allegheny General Hospital, the Pittsburgh Symphony Orchestra, Action-Housing, and the Western Pennsylvania Conservancy.
