Tiddeman, Mark (fl. c. 1724 - c. 1760)

Mark Tiddeman (fl. c. 1724 - c. 1760) was a British navigator, surveyor, chartmaker, and hydrographer active in the early 18th century. Tiddeman was sailing master of the English ship Tartar. From 1724 to 1728 he completed a hydrographic survey of New York Harbor and the mouth of the Chesapeake. These surveys were eventually adopted by Mount and Page for inclusion in the 1732 fourth book of the English Pilot. On returning to England Tiddeman completed several surveys of the Highlands of Scotland for Admiral Wagner, who was then stationed on the Coast of Scotland. On March 27th of 1741 he was commissioned as a Lieutenant in the Royal Navy. He later became a Captain and piloted several ships to and from the British West Indies.
