Professor, department chair, NASA researcher, study-skills expert, intelligent design theorist, leader in appropriate technologies for the developing world. Walter Bradley is all that, but also much more. Through his long list of achievements, he has remained a man of integrity, dedicated to truth and love, making the crucial difference in countless lives.


At the end of his life, the Apostle Paul wrote to his protégé Timothy, “I have fought the good fight, I have finished the race, I have kept the faith.” (2 Timothy 4:7) The same is true of the life of professor, humanitarian, and Christ-follower Walter Bradley.


It’s true from his days as a graduate assistant determined to share his love for Jesus with his first-ever class to becoming one of the most respected engineering professors in academia. It’s true whether he was leading a small Bible study for students in his home or defending intelligent design before large crowds of his academic peers. It’s true whether he was performing ground-breaking research for NASA or serving as an expert witness in the courtroom or empowering people in Africa with appropriate technologies.


Bradley has resolutely refused the idols of our age. It’s easy for a young academic to be swayed by campus politics, compromise one’s principles, and lose one’s witness for Christ. From his earliest days as a graduate student, Bradley made a deal with God: he would unashamedly share his faith with students and faculty, and he would not let academic ambition keep him from spending the time that his faith and family deserved. The day he could no longer keep that deal, he would leave the academy. He never had to.


Bradley’s academic and professional achievements are impressive. With a doctorate in materials science, this celebrated scientist and professor has spent more than 50 years in the classroom, at the laboratory, as a keynote speaker, and behind a keyboard co-authoring a bestselling book on intelligent design (The Mystery of Life’s Origin). 


But despite his academic and professional success, Walter and his wife, Ann, regard as their most important achievements the countless times they’ve been able to invest in the lives of students, colleagues, friends, neighbors, and people in the developing world, making a real difference for good.


In For a Greater Purpose: The Life and Legacy of Walter Bradley, authors Robert Marks and William Dembski detail the story of this remarkable man whose passion for God, science, and higher education provides as good an example as exists of someone who integrates faith and learning.
