Roald Hoffmann was born in 1937 in Złoczów, Poland. He came to the U. S. in 1949 and studied chemistry at Columbia and Harvard Universities (Ph.D. 1962). Since 1965 he has been at Cornell University, now as the Frank H. T. Rhodes Professor of Humane Letters Emeritus. He has received many honors, including the 1981 Nobel Prize in Chemistry (shared with Kenichi Fukui). "Applied theoretical chemistry" is the way Hoffmann likes to characterize the particular blend of computations stimulated by experiment and the construction of generalized models, of frameworks for understanding, that is his contribution to chemistry. The pedagogical perspective is very strong in his work. Notable at the same time is his reaching out to the general public; he participated, for example, in the production of a television course in introductory chemistry titled "The World of Chemistry." And, as a writer, Hoffmann has carved out a land between science, poetry and philosophy, through many essays and a number of books. Hoffmann began writing poetry in the mid-1970s, and has also written 3 plays (one with Carl Djerassi), which have been performed worldwide. Hoffmann is also a frequent contributor to American Scientist magazine.

Jo Ann Joselyn (SX 1968)
Jo Ann Joselyn grew up during a period of amazing firsts, when advances in science and space exploration captured the imagination of people around the world. "Sputnik was launched on my 14th birthday, and I knew then I was destined for space work," says Joselyn, who has had a 35-year career studying space weather. So it is fitting that Joselyn went onto capture some of her own "firsts." A 1965 University of Colorado-Boulder graduate in applied math, she became the first woman to earn a doctoral degree from the C.U. Department of Astrophysical and Planetary Science —the study of solar-planetary interactions. As a space scientist at the National Oceanic and Atmospheric Administration in Boulder, she is particularly proud of her work that showed that ejections of solar wind associated with disappearing solar filaments caused magnetic storms that can disrupt communications, electrical power transmission, space flight, and other emerging technologies. More recently, Joselyn also became the first woman to be elected secretary-general of the International Association of Geomagnetism and Aeronomy, and then the first woman and first American to be elected secretary-general of the International Union of Geodesy and Geophysics. Calling it "a second career in international coordination of science," the position presented new challenges in working with 65 member governments on geophysical projects.

Kassoy was elected an Associate Member of Sigma Xi while a Ph.D. graduate student in aerospace engineering at the University of Colorado in 1963. He was elected a full member in 1971, and was elected chapter president for the 1999-2001 program years. Subsequently he served for 10 additional years as vice president and continues as an active member on the executive board.  Kassoy is currently a Professor (emeritus) of Mechanical Engineering at the University of Colorado and the CEO of a small research business, "Kassoy Innovative Science Solutions".
