Ben Hogan's nine major championships speak for themselves, but he also had an authoritative voice when it came to golf instruction. Hogan wrote two books on the golf swing -- "Power Golf" in 1948 and "Five Lessons" in 1957 -- that are still sought after by golfers of all levels. Known for his meticulous practice habits, Hogan constantly worked on trying to perfect his swing and these books were his outlet to share the knowledge he'd gained with the general public. Along the way, Hogan's lessons were sporadically published in Golf Digest as well. Here, we look back at some of these gems that are just as applicable today as when he doled them out.
