Michael Francis Pennock (1945–2009) was the author of several bestselling textbooks for Catholic high schools, including, Encountering Jesus in the New Testament, Your Life in Christ, Our Catholic Faith, and three recent texts to support the new US Bishops’ curriculum framework. He remains one of the most respected names in catechetical circles. Pennock taught theology for more than thirty-five years, mostly at his beloved alma mater, St. Ignatius High School in Cleveland, Ohio. His students, numbering more than fifteen thousand, continue to pour out their remembrances and support for the man they called “Doc Pennock.”
