Peter Jay Gierasch (19 December 1941 – 20 January 2023) was an Americanastronomer andastrophysicist.
In 1962, Peter Jay Gierasch received his bachelor's degree in physics from Harvard University. He continued his studies at his alma mater and immediately commenced working towards a Ph.D. inapplied mathematics.[1]
Through a mutual friend, Gierasch was introduced to his wife of 59 years, Maida Wiesenthal. They dated for six months before deciding to marry in June 1964.[2]
In 1968, within the scope of a year, Gierasch finished his Ph.D. and promptly began his outstanding contribution to planetary sciences with the publishing of his first paper, "Martian thermal and dynamical structure (1968)".[3] The paper focused on the astrobiology of Mars and the planet's atmospheric wind conditions and was an enormous success. The work was the first to ever apply a systematic approach to the analysis of the relationship between the Martian surface and the planetary atmospheric conditions, highlighting the contrast shown to Earth.[4]
Gierasch published again in 1971, producing a comprehensive paper on the wind conditions of Mars with the astronomersJoseph Veverka andCarl Sagan. Three decades later, the theories presented by the paper were proved accurate by footage from exploration of the Martian atmosphere.[4]
Gierasch joined the Cornell faculty as a professor of astronomy in 1972 and began for NASA as a scientist on theVoyager spectrometer team in 1973.[1]
Gierasch was raised with two sisters, Molly Gierasch and Lila Gierasch. His mother, Marian Bookhout Gierasch, and sister Lila Gierasch studied atMount Holyoke College.[6] Lila followed Peter's footsteps and completed her post-graduate study at Harvard University.
Gierasch was married for 59 years to Maida Gierasch.[2] They had two children; their eldest son Adam Gierasch followed by their daughter Amanda.
Throughout his career, Gierasch contributed as an author or co-author to an impressive 64publications.
