Maull was born at Pilottown, near Lewes, Delaware, son of John and Mary Marsh Maull. His father was a shipwright who ran arms from the West Indies during the American Revolution. He died, so the story goes, when a ship's mast fell on him. During the American Revolution, Joseph Maull had an uncle, Nathaniel, who piloted ships for the American Committee of Safety, and another, James, who scouted the Delaware Bay for the British. Maull, himself, served in the 3rd Brigade of Delaware Militia, defending Lewes during the War of 1812.
Maull studied medicine under Dr. John Wolfe of Lewes and spent the rest of his life as a practicing physician from his home in Milton, Delaware. He married Penelope Shields in 1802 and they had two children, Susan and George. After her death, he married Sarah Davis Watson in 1820, and they had no children. They were members of St. Peter's Episcopal Church in Lewes.
Political career
Maull served in the state senate for 21 years, from the 1816 session through the 1824 session, again from the 1827 session through the 1830 session and finally from the 1839–40 session through the 1845–46 session. As he was Speaker during the last session, he became Governor of Delaware upon the death of Governor Thomas Stockton on March 2, 1846, serving until his own death on May 3, 1846. He was the seventh Governor of Delaware to die in office. Maull began his career as a Federalist, and joined the Whig Party with the party realignment of the 1830s. When he was governor he was opposed to the foreign policy of U.S. PresidentJames K. Polk, including the annexation of Texas.

Maull died at Lewes[citation needed] and is buried there at the St. Peter's Episcopal Churchyard.
