John Gill was born in Charlestown, Massachusetts in 1732. He was Benjamin Edes’ partner in the Boston Gazette, which was a decidedly rebel print before the war for independence began in the colonies. The two printed the paper together up until the American Revolution. From 1776 to 1785, Gill put his efforts into The Continental Journal.
Altogether, John Gill printed the Boston Gazette for 20 years — from 1755 to 1775. Edes left Boston when the Siege of Boston began in 1775. John Gill stayed and ceased his involvement with the Boston Gazette. It appears that Gill’s political positions began to waver and then change completely. There is some evidence that he and Gill were on opposite ends of the political spectrum once the war was over. They printed from different perspectives, at least.
John Gill and Edes later settled their rights to the paper, with Edes continuing production. In 1785, John Gill sold The Continental Journal. He died that same year.
