Robert Erskine (1735–1780) was a Scottish inventor and engineer who came to the British Thirteen Colonies in 1771 to run the ironworks at Ringwood, New Jersey, and later became sympathetic to the movement for independence.
 In 1776 during the American Revolutionary War, he designed an underwater cheval-de-frise installed across the Hudson River at the north end of Manhattan to prevent passage of British ships upriver.
 General George Washington appointed him as Geographer and Surveyor General of the Continental Army at the rank of colonel; Erskine drew more than 275 maps, mostly of the Northeast region.

William Brownie Garden (December 2, 1869 – 1960) was a Scottish inventor and entrepreneur.
 He is probably best known for his invention of the "revolving blackboard".
 Up until his death at age 90, in 1960, the ‘Inventor’ still worked at his own bench in the factory, from which came innovations like an improved saw which cut ten times quicker than any other, and an eight-wheeled car for faster cornering.
 For relaxation he produced scores of beautifully carved walking sticks, which he presented free to the older townspeople.
 His mind roamed the entire mechanical firmament.
 He was a dreamer with the most practical of brains, who, even in his youth, foresaw the future by drawing tentative plans for a vertical take-off aero engine.
Carmencita is an 1894 American short black-and-white silent documentary film directed and produced by William K.L. Dickson, the Scottish inventor credited with the invention of the motion picture camera under the employ of Thomas Edison.
