Persifor Frazer (August 9, 1736 – April 24, 1792) was an American farmer, soldier, and industrialist, and the founder of one of the most prominent families of Philadelphia, Pennsylvania.
He married Mary "Polly" Taylor on October 2, 1766, and managed a prosperous farm near Brandywine Creek.
Frazer became a leading regional political figure resisting the growing British power in the colonies.
In a letter to his wife in July 1776 Frazer expressed negative opinions towards the blacks serving in many New England regiments of the army.
[citation needed] His grandson Persifor Frazer Smith was a lawyer and member of the Pennsylvania legislature.
