Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Mary Engle Pennington (October 8, 1872 - December 27, 1952) was an American bacteriological chemist and refrigeration engineer. Mary Engle Pennington was born in Nashville, Tennessee; her parents were Henry and Sarah B. (Malony) Pennington. Shortly after her birth, her parents moved to Philadelphia, Pennsylvania, to be closer to Sarah Pennington's Quaker relatives. Mary Pennington demonstrated an early interest in chemistry. She entered the University of Pennsylvania in 1890 and completed the requirements for a B.S. degree in chemistry with minors in botany and zoology in 1892. However, since the University of Pennsylvania did not grant degrees to women at this time, she was given a certificate of proficiency instead of a degree.
