Energy recounts the life of Dr. John J. McKetta Jr., a first-generation Ukrainian American coal miner who worked his way up from the mines to become the world's foremost energy expert, a university dean, an encyclopedia editor, and one of the most widely known and respected professors in his field. To honor his one hundredth birthday in 2015, thousands of his former students raised more than $25 million to celebrate his contributions to their lives and to chemical engineering at the University of Texas at Austin, which rechristened his home department the John J. McKetta Jr. Department of Chemical Engineering. In this biography, granddaughter Elisabeth Sharp McKetta retraces Dr. McKetta's path to becoming the godfather of modern chemical engineering. She describes how he dedicated his life to supporting students throughout their careers, becoming legendary for phoning scores of them on their birthdays every year, while also showing Americans how to produce and use energy efficiently. John J. McKetta Jr.'s fascinating story has been the subject of hundreds of articles and interviews, and now Energy is the first full-length book about his remarkable life.
