Pulaski Bank was founded in 1922 by a group of Polish-American citizens who joined together to establish a Savings and Loan Association in St. Louis. The purpose of this Association was to form a financial organization to allow its members to achieve financial freedom and homeownership. The name was chosen in honor of General Casimir Pulaski, an Old World nobleman and hero of the American Revolution.

Pulaski was born in 1748, the oldest of three sons of Count Josef Pulaski. In 1775, he met an American emissary, Benjamin Franklin, and learned of the American colonists struggle for independence. He proceeded to America, joined Washington's Army and was granted a commission as Brigadier General of Cavalry, the first of such rank in the Continental Army. After a brave defense of Charleston, South Carolina, General Pulaski died with his cavalry in battle at Savannah, Georgia in 1779.
