Della M. Roy, 94, passed away on March 27, 2021. She graduated from the University of Oregon in 1947 with a B.S. in chemistry, Phi Betta Kappa. Enrolled at the Pennsylvania State College, under Prof. E.F. Osborn, future director of U.S. Bureau of Mines, Della received an M.S. in Minerology in 1949. In the interim, she shared an office and lab with another graduate student, Rustum Roy, leading to marriage in June 1948. The couple then moved to live and work in India in 1949, returning to Penn State in 1950 where Rustum joined the faculty and Della completed a PhD (1952) in Minerology.

On the path to becoming an international leader in the field of cement chemistry, her career was marked by a series of unique milestones and pioneering firsts: In 1965, the mineral, Dellaite, was named in her honor; her 1987 induction into the National Academy of Engineering, represented the first Penn State female, the third female academic, and formed the first spousal couple (along with Rustum) to be so honored; with her colleague, Kathleen Mourant, she started and edited the first scientific journal in the field of cement and concrete for many decades.

In a research and teaching career at Penn State, spanning over 50 years, she rose to the rank of Full Professor in 1975. Over the course of her career, she became renowned for her work in advanced concrete materials for pavements, chemically bonded cements, ancient cement-based building materials, synthetic porous biomaterials for hard tissue implants and prosthetics, cement materials for nuclear waste isolation, and high temperature cements for geothermal wells, among others.

In "retirement," as well as maintaining active research at Penn State, she joined ASU and held a part-time joint appointment in the School of Sustainable Engineering and the Built Environment and the School of Mechanical Aerospace, Chemical and Materials.

Among numerous national and international awards, she was elected to the World Academy of Ceramics as its first female member, she received the Jepson Medal (1982) and Copeland award (1987) of the American Ceramic Society, and became honorary member of the Institute for Concrete Technology (1987).

In 2012 she was a co-recipient of the first annual Golden Goose Award established by the United States Congress to honor federally funded research leading to major breakthroughs in scientific, technological, medical, public health, and other fields of benefit to the public.

Della is survived by two sons, two grandchildren and other relatives. A memorial service will be announced to take place later this year.
