Lynn post office to be rededicated to Thomas P. Costin Jr.

The Lynn Post Office will be rededicated on Friday to the city’s former mayor and postmater, Thomas P. Costin Jr., the U.S. Postal Service announced.

When he was elected in 1956 at age 29, Costin was the youngest serving mayor in Lynn’s history. Costin headed a registration drive for then-candidate John F. Kennedy in 1958, according to a Globe article at the time. After he was elected, President Kennedy appointed Costin to Postmaster of Lynn in 1961.

“He would hold that position until his retirement in 1992, helping to usher in many changes in the way today’s Postal Service operates,” the postal service said in a statement.

After retiring as postmaster, Costin remained active in civic affairs on the North Shore. He was a key advocate for the Lynn Business Partnership’s long effort to extend rapid transportation to Lynn, one of the state’s largest cities.

Now, in retirement, Costin will be honored by city he served his entire life.

Representative Seth Moulton, a Salem Democrat, filed a bill last June to designate the Lynn post office the “Thomas P. Costin Jr. Post Office Building.”

The bill was co-sponsored by the other eight-members of the state’s all-Democratic congressional delegation. President Trump signed the bill into law in December.

A rededication ceremony will take place on May 24 in front of the post office at 51 Willow St, in Lynn at 11:00 a.m.

Senator Edward Markey and Moulton expected to be in attendance. In a tribute to their grandfather, Costin’s grandchildren will read the Pledge of Allegiance at the ceremony.
