Biddle was born to a wealthy old Quaker family on December 24, 1745, in Philadelphia, Province of Pennsylvania in what was then British America. He was the son of William Biddle, 3rd (1698–1756) and Mary (née Scull) Biddle (1709–1789). His siblings included: Lydia Biddle, who married William Macfunn; John ”Jacky” Biddle, who married Sophia Boone; Edward Biddle, a lawyer, soldier, delegate to the Continental Congress,[1] who married Elizabeth Ross, sister of George Ross; Charles Biddle, and Nicholas Biddle, Revolutionary War Navy captain.[2]
During the American Revolutionary War, Biddle was a captain in the merchant service and participated in the work around of the British fleet's blockade of American ports. He volunteered in the Quaker Light Infantry and, in 1778, he served under his brother, Commodore Nicholas Biddle, aboard the USS Randolph.[4]
Although Biddle vacated his seat at Council on October 13, 1787, the Commonwealth of Pennsylvania records that his Vice-Presidential term extended to October 31, the date of the next Presidential and Vice-Presidential elections. Biddle was elected Secretary of the Council on October 23.
