Horvath didn't disclose the cause of death.

Fans immediately expressed their love for the 'gifted storyteller' who wrote more than two dozen novels, including his 1992 adventure story, Sahara.

Sahara was turned into a feature film in 2005, starring McConaughey, Steve Zahn and Penélope Cruz.

The book is one of Cussler's famed Dirk Pitt novels that follows Pitt through the African desert in search of a ship with treasure rumored to have vanished long ago.

Cussler began writing in 1965 and published his first novel, The Mediterranean Caper, featuring the character Dirk Pitt in 1973.

In 1996, he released his first piece of non-fiction, The Sea Hunters. The Board of Governors of the Maritime College, State University of New York later considered The Sea Hunters in lieu of a Ph.D. thesis and awarded Cussler a Doctor of Letters degree in May of 1997.

It was the first time since the college was founded in 1874 that such a degree was bestowed.

Cussler also founded the National Underwater & Marine Agency, (NUMA) a nonprofit organization that dedicates itself to American maritime and naval history.

After the organization was established, Cussler and his crew of marine experts and volunteers discovered more than 60 historically significant underwater wreck sites.

Among their discoveries was the C.S.S. Hunley, the first submarine to sink a ship in battle and the U-20, the U-boat that sank the Lusitania.

Cussler was also a classic automobile collector.

He established the Cussler Museum in Colorado that's dedicated to the preservation of rare and vintage automobiles from all over the world.
