Thomas C. O'Sullivan

Thomas C. O'Sullivan (c. 1858 Michigan – July 29, 1913 Spring Lake, Monmouth County, New Jersey) was an American lawyer and politician from New York.

He was Principal of the high school in Burlington, and worked during the summer vacations in a factory.

Then he taught English, French and Latin at Wadham's Academy in Ogdensburg, New York, and later at St. Joseph's College in Burlington.

For his work in religious and charitable organizations, he was made a Knight of St. Gregory by Pope Pius X in 1908.

In 1907, he suffered "from an attack of pneumonia," which "affected his sight, and finally necessitated an operation for the removal of an eye."
