The son of an Air Force sergeant, Randal J. Kirk was born March 10, 1953, on a military base in Pleasanton, California. He spent most of his childhood in Virginia and attended Radford University, graduating with a degree in business in 1976. Three years later, he received a degree from the University of Virginia School of Law.

While practicing as an attorney, he partnered with local investor, John Gregory, to found perishable-drug distributor General Injectables and Vaccines in 1983. He sold it 15 years later for $65 million in cash. He donated $1 million to his alma mater, Radford University, the same year. It was the largest gift the school had ever received from an alumnus.

After the sale, Kirk founded New River Pharmaceuticals, focusing on making safer, improved versions of existing drugs. The company's biggest success came with Vynase, an attention deficit disorder medication. Shortly after the treatment won FDA approval in 2007, Kirk sold the company to Dublin, Ireland-based Shire for $2.6 billion. He had another payout in 2011, when he sold an antidepressant maker Clinical Data to New York-based Forest Laboratories for $1.2 billion. Between the two deals, Kirk received more than $1.8 billion.

Over the next few years, Kirk invested about $200 million into Intrexon, a biotechnology company that designs and makes artificial cell systems for use in human therapies, agriculture, industrial products and other applications. He owns more than half of the Germantown, Maryland-based company that sold shares to the public in August 2013.

The billionaire, who is divorced and has four children, lives in Florida and Virginia.
