Alongside the Founding Fathers who are household names, numerous lesser known founders were also instrumental in the establishment of the United States of America. This book presents the comprehensive biography of one such neglected man, Pennsylvania's Thomas Mifflin. With the sole exception of George Washington, Thomas Mifflin was the only founder to rise to both the highest military rank in the American army—major general—as well as the highest position in the new nation's civilian government—President of the Continental Congress. George Washington's first military aide and the first Quartermaster General of the Continental Army, Mifflin signed both the U.S. constitution and the peace treaty with Great Britain, which ended the Revolutionary War. He was elected the first governor of Pennsylvania and re-elected twice by landslide margins. Drawing on all available primary sources and a wealth of secondary sources, this exhaustively researched biography presents the life, accomplishments and legacy of an influential, Founding Father too often overlooked in recent times.
