From the 'Turnback Tuesday' archives: Derby's first mayor
This week's "Turnback Tuesday" features an image of Derby's first mayor, Thomas Jefferson O'Sullivan.
Although Derby was officially recognized by the state of Connecticut in 1675, it wasn't until after Ansonia's separate incorporation as a city in 1893 that Derby's current boundaries were set. And after which time Dr. O'Sullivan was elected mayor of the City of Derby.
Born in 1852 in Preston, O'Sullivan first attended medical school in Burlington, Vermont then eventually earned his medical degree in New York. After graduating in 1876, he practiced in Worcester, Mass. for two years before returning to Connecticut and setting up a new practice in Derby.
He remained in Derby until his death around 1900.

Sharing 'Turnback Tuesday' 2015 archives: Derby Post Office history
This week's "Turnback Tuesday" is a picture of the Derby Post Office on Olivia Street built in 1932. The first Derby Post Office was actually on Main Street and was built in 1798.
The current Post Office is eligible for the National Register of Historic Places. It served as a fall-out shelter during World War II and has changed from this picture since being made ADA compliant in the 1990s.
