Few American lives have been as celebrated--or as closely scrutinized--as that of Benjamin Franklin. Yet until now Franklin's biographers have downplayed his interest in mathematics, at best portraying it as the idle musings of a brilliant and ever-restless mind. In Benjamin Franklin's Numbers, Paul Pasles reveals a side of the iconic statesman, scientist, and writer that few Americans know--his mathematical side. In fact, Franklin indulged in many areas of mathematics, including number theory, geometry, statistics, and economics. In this generously illustrated book, Pasles gives us the first mathematical biography of Benjamin Franklin. He draws upon previously unknown sources to illustrate Franklin's genius for numbers as never before. Magic squares and circles were a lifelong fascination of Franklin's. Here, for the first time, Pasles gathers every one of these marvelous creations together in one place. He explains the mathematics behind them and Franklin's hugely popular Poor Richard's Almanac, which featured such things as population estimates and a host of mathematical digressions. Pasles even includes optional math problems that challenge readers to match wits with the bespectacled Founding Father himself. Written for a general audience, this book assumes no technical skills beyond basic arithmetic. Benjamin Franklin's Numbers is a delightful blend of biography, history, and popular mathematics. If you think you already know Franklin's story, this entertaining and richly detailed book will make you think again.

A funny, entertaining introduction to Ben Franklin and his many inventions, including the story of how he created the "magic square." A magic square is a box of nine numbers arranged so that any line of three numbers adds up to the same number, including on the diagonal! Teachers and kids will love finding out about this popular teaching tool that is still used in elementary schools today!

"Was Benjamin Franklin a British spy? This is the startling but all too legitimate question investigated in this complete reappraisal of one of America's most illustrious founding fathers. Franklin has traditionally been portrayed as a dedicated servant of the United States during the turbulent years of the nation's birth. Now in Code Number 72 / Ben Franklin: Patriot or Spy?, author-historian Cecil B. Currey has brought to life an entirely different story."--Book Jacket.

In this engaging study of the much-loved statesman and polymath, Robert Middlekauff uncovers a little-known aspect of Benjamin Franklin's personality—his passionate anger. He reveals a fully human Franklin who led a remarkable life but nonetheless had his share of hostile relationships—political adversaries like the Penns, John Adams, and Arthur Lee—and great disappointments—the most significant being his son, William, who sided with the British. Utilizing an abundance of archival sources, Middlekauff weaves episodes in Franklin's emotional life into key moments in colonial and Revolutionary history. The result is a highly readable narrative that illuminates how historical passions can torment even the most rational and benevolent of men.

Between 1771 and 1790, American Founding Father Benjamin Franklin sat down to record the important events of his life, from his childhood in Boston to his work as a printer in Philadelphia, to his trips to Paris and his plans for the first public library. The story of the invention of the Franklin stove, the first Poor Richard's Almanac, and his experiments with electricity are all included here. His "Project for Moral Perfection"—a list of desirable virtues and steps to achieve them—influenced the modern self-help genre. Hundreds of years later, Franklin's account of his rise from middle-class obscurity to become a world-renowned scholar and civic figure continues to promote the American Dream. First published in 1791, this unabridged version of Franklin's autobiography is taken from the 1909 copyright edition.
