Opportunity Knocks (1961) This 1960s student film documents some of the professional training offered to students at Fort Worth's I.M. Terrell High School, from stenography and accounting to cosmetology and auto-mechanics. I.M. Terrell High School opened in 1882 as the East Ninth Street Colored School—the first free public school for African Americans in Fort Worth. The school closed in 1973 following racial integration.
