Sam Greenlee may be most remembered for penning the Black Power era classic "The Spook Who Sat by the Door." But his family is asking for help to properly memorialize the writer and filmmaker, who passed away late last month at age 83.

The family has announced that a public memorial will be held on Friday, June 6 at Chicago’s DuSable Museum starting at 6:30pm. But they’re trying to raise $5,000 to help cover the costs of the service and help wrap up some of Greenlee’s unfinished work. Read more at their fundraising page.
