A familiar face to a generation of Chicago children has died. Bill Jackson was a mainstay of children’s television in Chicago in the 1960s and ‘70s. His most memorable programs were “The BJ and Dirty Dragon Show” on WGN-TV and WFLD, and “Gigglesnort Hotel” on WLS-TV. Jackson worked as a puppeteer, cartoonist and kids’ show host, playing the mayor of a town filled with his puppet creations.
