Augustine "Og" Mandino II (December 12, 1923 – September 3, 1996) was an American author. He wrote the bestselling book The Greatest Salesman in the World. His books have sold over 50 million copies and have been translated into over 25 languages. He was the president of Success Unlimited magazine until 1976 and was inducted into the National Speakers Association's Hall of Fame. Life and career According to the 1930 U.S. Census, Mandino was born in Natick, Massachusetts, on December 12, 1923, to parents Silvio and Margaret Mandino. He was named Augustine after his Italian paternal grandfather. Mandino was once the editor of his high school paper and planned to attend the University of Missouri's journalism school. In 1940, before he entered college, his mother died from a massive heart attack. He decided to work in a paper factory until 1942. Afterward, he joined the United States Army Air Corps where he became a military officer and a bombardier. He flew for 30 bombing missions over Germany on board a B-24 Liberator during World War II. During this time, he flew with fellow pilot and movie star James Stewart. After his military duties, Mandino became an insurance salesman. One wintry November morning in Cleveland, he contemplated committing suicide. But as he sorted through several books in a library, volumes of self-help, success and motivation books captured his attention. He selected some titles, went to a table and began reading. He followed his visit to the library with more visits to many other libraries around the United States. He read hundreds of books that dealt with success, a pastime that helped him alleviate his alcoholism. It was in a library in Concord, New Hampshire, where he found W. Clement Stone's classic, Success Through a Positive Mental Attitude, a book that changed Mandino's life. The author's biographical information with this book indicated that Stone was the owner of the Combined Insurance Company. Mandino decided to obtain a sales position with the company when he was 32 years old. Within a year, Mandino was promoted to sales manager and breaking sales records. A pamphlet that he wrote concerning sales in rural markets got him a job in promotional writing and a position on W. Clement Stone's magazine Success Unlimited. By 1966, Mandino was Executive Editor of the magazine and helped edit an anthology of articles from the magazine, A Treasury of Success Unlimited.
