Rev. Hitchcock received his doctorate from Brown University in 1788 and maintained close connections with the school throughout his life. He was also involved in the cause of education, along with President James Manning (1738-1791) of Brown University, Moses Brown (1738-1836) and other prominent Providence citizens. By the time of his death, he was successful in obtaining the establishment of a public school system in Providence. Besides this endeavor, Rev. Hitchcock was a member of the Pennsylvania Society for Promoting the Abolition of Slavery. He himself had purchased a man from slavery, Ceasar Hitchcock, whom he manumitted and remembered in his last will and testament for his faithful service. Rev. Hitchcock died in Providence, R.I. on February 27, 1803.
Portions of his diaries were published by the RIHS in 1899, and can be read online.
