Royston Campbell Crane (November 22, 1901 – July 7, 1977), who signed his work Roy Crane, was an American cartoonist who created the comic strip characters Wash Tubbs, Captain Easy and Buz Sawyer. He pioneered the adventure comic strip, establishing the conventions and artistic approach of that genre. Comics historian R. C. Harvey wrote, "Many of those who drew the earliest adventure strips were inspired and influenced by his work."

Born in Abilene, Texas, Crane grew up in nearby Sweetwater. When he was 14, he took the Charles N. Landon correspondence course in cartooning. He initially attended college at Hardin-Simmons University in Abilene and later the University of Texas, where he was a member of Phi Kappa Psi fraternity. At 19, he studied for six months at the Academy of Fine Arts in Chicago. His early work history was a checkered one, including pitching tents for a Chautauqua, a seaman's berth and a stint riding the rails. In 1922, he began his newspaper cartooning career on the New York World, where he assisted H. T. Webster. Crane was also influenced by the work of cartoonist Ethel Hays, especially in the drawing of women.

In 1924, Crane approached Charles N. Landon, an editor at the Newspaper Enterprise Association. Landon and Crane discussed a strip titled Washington Tubbs II about a diminutive goof employed at a grocery store. With the title shortened to Wash Tubbs, the strip debuted April 14, 1924. After four months, Crane tired of the gag-a-day format and sent his pint-size hero hunting for a treasure buried somewhere on a South Pacific island. The strip then evolved into a rollicking adventure yarn, with Crane introducing innovations in storytelling, sound effects and layouts, as noted by pop culture historian Tim DeForest:

With the introduction in 1929 of the raffish soldier of fortune, Captain Easy, Crane heightened the spirit of adventure and later created a Sunday strip focusing on Captain Easy. NBM Publishing's Flying Buttress Classics Library reprinted Crane's complete run of Wash Tubbs and Captain Easy in a series of 18 volumes. Bill Blackbeard's introductions to these books contain biographical and critical material.

World War II rendered the comic-opera settings of Tubbs' adventures frivolous, and the strip took on a new tone. In 1943, an offer from Hearst's King Features Syndicate persuaded Crane to jump ship and create a more realistic comic strip, Buz Sawyer. He left Wash Tubbs in the hands of his assistant, Leslie Turner, a boyhood friend who had shared the hobo life with him.

Crane, an excellent draftsman despite his deceptively cartoonish style, introduced more illustrative shading techniques to the daily comics page. He progressed from line drawings with crosshatching to grease pencil on textured paper, then to Benday Dots and finally to Craftint Doubletone Paper. The Craftint paper, when brushed with chemical solutions, revealed either one or two layers of diagonal shading. Under Crane's brush, the technique yielded scenes of dramatic atmosphere, such as junglescapes fading into the misty distance. As he had done with Wash Tubbs, Crane traveled to various locations to research his plot lines and visuals. According to Crane: "In using benday, at first I thought in terms of blacks, grays, and white. Years of indifferent results and frustration followed. Gradually, black became less important. Today white is not just something to bring out the color of black... on the contrary, black is something to bring out the color of white".

Crane progressively relinquished his cartooning to assistants, and he died in Orlando, Florida in 1977.

Today, Buz Sawyer has been resurrected digitally as one of the vintage strips in King Features' emailed DailyINK subscription service.
