Emil J. Slowinski
Emil J. Slowinski, Ph.D., earned a bachelor of science from Massachusetts State College in 1946 and a doctorate in physical chemistry from the Massachusetts Institute of Technology in 1949. Over the course of his prolific teaching career, he taught at Swarthmore College, the University of Connecticut and Macalester College. His sabbatical leaves were taken at Oxford University and the University of Warsaw. He was a co-author, working with other authors like Bill Masterton and Wayne Wolsey, of more than 25 books in various areas of general chemistry. Even after retiring, Dr. Slowinski was actively involved in editions one through nine of Chemical Principles in the Laboratory, and after leaving active writing he offered insights, advice and support to his coauthors; he remains the main content source of this edition. Dr. Slowinski was an Emeritus DeWitt Wallace Professor of Chemistry at Macalester College until his death in 2015.
Wayne C. Wolsey
Wayne C. Wolsey, an inorganic chemist, received his B.S. from Michigan State University in 1958 and his Ph.D. from the University of Kansas in 1962. He joined the Macalester College faculty in 1965 and is now in "semi-retirement." His last three sabbaticals were spent at the Oak Ridge National Laboratory. In 2001-2002, he investigated various complexing agents for their effectiveness in dissolving calcium oxalate kidney stones, in collaboration with a former student, now a urologist. He has received various awards, including the Minnesota College Science Teacher of the Year in 1989; Macalester's Thomas Jefferson Award in 1993; designation as a MegaMole contributor to Minnesota Chemical Education in 1997; and an award from the Minnesota State AAUP Conference in 2001 for his support of academic freedom and shared governance. He remains professionally active in a number of scientific organizations.
Robert C. Rossi
Robert C. Rossi, Ph.D., is an entrepreneur in technology, education and applied science. He earned his bachelor of science in chemical engineering from the University of Wisconsin, Madison. Upon graduation he joined the Peace Corps and served as a teacher in the Fiji Islands. He then joined the California Institute of Technology, teaching and researching in the fields of applied photoelectrochemistry and semiconductor physics and eventually earning a doctorate in 2001. After several years teaching as a visiting professor at Carleton College, he moved to Macalester College, where he served as the Laboratory Supervisor in the chemistry department from 2003 to 2014. In 2011 he became a co-author of Chemical Principles in the Laboratory, with his contributions first appearing in the 10th Edition.
