Rand's contemporary admirers included fellow novelists, such as Ira Levin, Kay Nolte Smith and L. Neil Smith; and later writers such as Erika Holzer and Terry Goodkind have been influenced by her. Other artists who have cited Rand as an important influence on their lives and thought include comic book artist Steve Ditko and musician Neil Peart of Rush, although he later distanced himself. Rand provided a positive view of business and subsequently many business executives and entrepreneurs have admired and promoted her work. John Allison of BB&T and Ed Snider of Comcast Spectacor have funded the promotion of Rand's ideas, while Mark Cuban (owner of the Dallas Mavericks) as well as John P. Mackey (CEO of Whole Foods) among others have said they consider Rand crucial to their success.
