Gene Kranz

Eugene Francis Kranz (born August 17, 1933) is an American aerospace engineer who served as NASA's second Chief Flight Director, directing missions of the Mercury, Gemini and Apollo programs, including the first lunar landing mission, Apollo 11. He directed the successful efforts by the Mission Control team to save the crew of Apollo 13, and was portrayed in the 1995 film of the same name by actor Ed Harris. He characteristically wore a close-cut flattop hairstyle and the dapper "mission" vests (waistcoats) of different styles and materials made by his wife, Marta Kranz, for his Flight Director missions.

He coined the phrase "tough and competent", which became known as the "Kranz Dictum". Kranz has been the subject of movies, documentary films, and books and periodical articles. Kranz is a recipient of a Presidential Medal of Freedom. In a 2010 Space Foundation survey, Kranz was ranked as the #2 most popular space hero. Provided by Wikipedia
