John and Mary's College, named in their honor by its founder Benjamin Rush and later renamed Dickinson College. The Dickinsons also donated 500 acres (2 km²) in Carlisle, Pennsylvania, land originally inherited and managed by Mary Norris, to the new college. United States Constitution After his service in Pennsylvania, Dickinson returned to Delaware, and lived in Wilmington. He was quickly appointed to represent Delaware at the Annapolis Convention, where he served as its president. In 1787, Delaware sent him as one of its delegates to the Constitutional Convention of 1787, along with Gunning Bedford, Jr., Richard Bassett, George Read, and Jacob Broom. There, he supported the effort to create a strong central government but only after the Great Compromise assured that each state, regardless of size, would have an equal vote in the future United States Senate. As he had done with the Articles, he also carefully drafted it with the term "Person" rather than "Man" as was used in the Declaration of Independence. He prepared initial drafts of the First Amendment. Following the Convention he promoted the resulting Constitution in a series of nine essays, written under the pen name Fabius. In 1791, Delaware convened a convention to revise its existing Constitution, which had been hastily drafted in 1776. Dickinson was elected president of this convention, and although he resigned the chair after most of the work was complete, he remained highly influential in the content of the final document. Major changes included the establishment of a separate Chancery Court and the expansion of the franchise to include all taxpayers, except blacks and women. Dickinson remained neutral in an attempt to include a prohibition of slavery in the document, believing the General Assembly was the proper place to decide that issue. The new Constitution was approved June 12, 1792. Dickinson himself had freed his slaves conditionally in 1776 and fully by 1787. Once more Dickinson was returned to the State Senate for the 1793 session, but served for just one year before resigning due to his declining health. In his final years, he worked to further the abolition movement, and donated a considerable amount of his wealth to the "relief of the unhappy". In 1801, Dickinson published two volumes of his collected works on politics. Death and legacy Dickinson died at Wilmington, Delaware and was buried in the Friends Burial Ground. In an original copy of a letter discovered November 2009 from Thomas Jefferson to Joseph Bringhurst, caretaker of Dickinson in his later years, Jefferson responded to news of Dickinson's death: "A more estimable man, or truer patriot, could not have left us. Among the first of the advocates for the rights of his country when assailed by Great Britain, he continued to the last the orthodox advocate of the true principles of our new government and his name will be consecrated in history as one of the great worthies of the revolution." He shares with Thomas McKean the distinction of serving as Chief Executive of both Delaware and Pennsylvania after the Declaration of Independence. Dickinson College and Dickinson School of Law (now of the Pennsylvania State University), separate institutions each operating a campus located in Carlisle, Pennsylvania, on land inherited and managed by his wife Mary Norris, were named for them. Dickinson College was originally named "John and Mary's College" but was renamed to avoid an implication of royalty by confusion with "William and Mary." And along with his Letters from a Farmer in Pennsylvania, Dickinson also authored The Liberty Song. Dickinson Street in Madison, Wisconsin is named in his honor, as is John Dickinson High School in
