In The World of William Penn Foster explores the wide sphere of the humble Quaker, William Penn. From the courtyards of the Sun King to the royal chambers of Charles II, Penn was a "Friend" of kings and princes, scientists and Native Americans. A member of the Royal Society, Penn knew Edmund Halley and Isaac Newton. He met Peter the Great while the Czar was visiting London and introduced him to Quaker ideas. As the founder of Pennsylvania, Penn treated the Native American tribes with dignity and respect and by his integrity established the longest standing peace treaty between European settlers and Native Americans. His commitment to religious freedom became a cornerstone of American democracy. In her inimitable fashion, Foster has brought Penn's story to a new generation of readers. --Rea Berg, Editor 2008
