Hilary Hinton "Zig" Ziglar (November 6, 1926 – November 28, 2012) was an American author, salesman, and motivational speaker. "Zig" Ziglar was born prematurely in Coffee County, Alabama, to John Silas Ziglar and Lila Wescott Ziglar. He was the tenth of 12 children, and the youngest boy.

In 1931, when Ziglar was five years old, his father took a management position at a Mississippi farm, and his family moved to Yazoo City, Mississippi, where he spent most of his early childhood. The next year, his father died of a stroke, and his younger sister died two days later.

Between 1943 and 1945, he participated in the Navy V-12 Navy College Training Program at the University of South Carolina in Columbia, South Carolina.

Ziglar dropped out of college in 1947 and moved to Lancaster, South Carolina, where he took up a job as a salesman with the WearEver Cookware company. Ziglar was promoted to field manager and eventually divisional supervisor in 1950.

While working at the company, Ziglar became interested in self-help and motivational speaking and began giving speeches of his own. With Richard "Dick" Gardner and Hal Krause, Ziglar was a charter member in the establishment of American Salesmasters in 1963. The company's objective was to raise the image of salespeople in America by providing seminars. They began with cities across the South and Midwest (Memphis, Atlanta, Kansas City, St. Louis, Chicago, Denver, etc.), featuring speakers such as Ziglar, Norman Vincent Peale, Ken McFarland, Cavett Robert, Bill Gove, Maxwell Maltz, and Red Motley. They booked an auditorium, put together a slate of speakers and contacted local businesses to sell tickets. Audiences included insurance agents, car salesmen, financial advisors, entrepreneurs, small business owners and curiosity seekers.

Ziglar went on to speak extensively for audiences of the National Association of Sales Education (NASE), founded by Dick Gardner in 1965, and also became a major sales trainer for Mary Kay Cosmetics. In 1968, he became a vice president and training director for the Automotive Performance Company and moved to Dallas, Texas. The company went bankrupt two years later.

He later founded the Zigmanship Institute, later known as Ziglar, Inc. Subsequently, Ziglar spoke extensively at seminars for motivational speaker Peter Lowe and eventually signed an exclusive agreement to support Peter Lowe events.

In addition to speaking, Ziglar wrote over 30 books. His first book, See You at the Top, was rejected 39 times before it was published. It is still in print.

In Addison, Texas, Ziglar employed and trained several speakers, including Will Harris.

In 2007, a fall down a flight of stairs left him with short-term memory problems. Nonetheless, Ziglar continued taking part in motivational seminars until he retired in 2010.
