Henri Pachard, Jackson St. Louis and Crystal Blue were the pseudonyms of the American film director Ron Sullivan (June 4, 1939 – September 27, 2008).

[3][4] In the late 1960s, using his real name, Sullivan directed a number of sex-and-sadism Sexploitation films for the then-thriving 42nd Street grindhouse market.

This was followed by The Bizarre Ones (1967), Scare Their Pants Off (1968), and This Sporting House, with future adult star Jennifer Welles, in 1969.

He also made numerous bondage-discipline features, particularly for the long-running Dresden Diary series, and many spanking fetish videos such as Blazing Bottoms and Smarty Pants!

In May 2008 it was reported that Sullivan/Pachard was gravely ill from cancer, with an open call to others in the industry to employ his wife Deloras as a cameraman or as a film editor to help offset his medical expenses.
