"During his four-day visit in Denver, Mr Katz gave wonderful slide presentations, now adapted to PowerPoint, that provided information seldom addressed or acknowledged in the classroom or society at large, and whihc inlcuded rare photographs that reflected the authenticity of his words...I personally found him to be warm and engaging and really able to reach people. His wealth of knowledge and the striking images he provided were powerful in and of themselves."
— Jacquelyn Benton, Professor of African American Studies, The Metropolitan State College of Denver
