William Edgar Marshall was born to Scottish parents in New York City in 1837. At a young age, he moved to Washington, D.C., where he earned a living as a watchmaker. He then worked for the US Treasury Department, where he learned how to engrave portraits. In 1858 he was given a rare opportunity to work for the American Bank Note Company, where he spent “several years and became one of its best engravers." At the age of 21, he set off for Paris, where he planned to learn how to become a great painter.
