Obituary of Eli Reshotko

Eli Reshotko died peacefully in his home surrounded by family on December 6, 2025. He was born to Sarah and Max Reshotko on November 18th, 1930, in the Bronx, shortly after their immigration from Poland. The child of a tailor and a seamstress, Eli spent his formative years in Spanish Harlem, where his parents owned a dry-cleaning business. Eli was accepted into Bronx High School of Science and then attended the Cooper Union to study engineering. While he was in high school and college, he also attended Herzliya Hebrew Teachers College in New Yor,k where he was trained in Hebrew Language, Bible, Religion, Art, Drama, History, and general Jewish culture--and played basketball.  He earned a teaching credential there.

Eli received a master's degree from Cornell University and moved to Cleveland to work for NACA (the precursor of NASA).  He then went to Caltech on a Guggenheim Fellowship.  He returned to Cleveland and continued to work for NASA. In 1964, he joined the engineering faculty at Case Western Reserve University; he chaired his department for 12 years and then became the Kent H. Smith Professor of Engineering.  He served as interim Dean for two of his 38 years there.

Eli made seminal contributions in aerodynamics and fluid mechanics throughout his career. He is internationally recognized for his pioneering research on compressible boundary layers, their stability, and transition. A NASA colleague once noted that “Eli Reshotko’s outstanding characteristic is deep understanding of flow physics along with the ability to apply his understanding toward practical applications, providing solutions and methods that advanced the state of the art in aerodynamics.” His students and colleagues respected him as a great mind, and an engaged, honest, and deft leader, colleague, and mentor. In 2016, he was inducted into the NASA Hall of Fame. Further awards and honors include a lifetime achievement award from Cooper Union at the age of 89, election as Fellow of ASAA, ASME, APS, AAAS, and the American Academy of Mechanics, the AIAA Fluid and Plasma dynamics Award, the AIAA Dryden Lectureship, and the APS Otto Laporte Award.  He was designated an Aerospace Engineering Honorary Engineer of Texas A&M. He received the Albert Nelson Marquis Lifetime Achievement Award from Marquis Who’s Who and the CUAA Gano Dunn Award.

Eli met Adina Venit at the age of 18 at Habonim Summer Camp; this commenced their relationship, which led to 67 years of marriage, until her death in 2020.  Adina was adventurous enough to visit him in Ithaca and Cleveland before she was 18. They married in 1953 and took a long and habit-forming trip through Europe and to Israel in 1956 before starting their family in Pasadena and then returning to Cleveland to complete and raise their family.

Despite his rigorous professional schedule, Eli sang with the Cleveland Orchestra Chorus, played recorder at home and in a Collegium Musicum, acted in Yiddish theater at the JCC, served on the Cleveland Board of Jewish Education, and guided the Cleveland College of Jewish Studies as a member of their board and even as interim president at a moment of administrative crisis.  He also played tennis and water-skied. He fought for Civil Rights alongside Adina. The family made frequent trips to NYC, upstate New York, "out-west" (camping), Florida, and Canada.  Eli and Adina brought their family to Israel for a full year's sabbatical at the Technion and then took a ferry to Genoa so they could go on a 6-week drive through Europe with their three daughters, one of their nieces, and Adina's father. 

Eli's career took him away from home many weeks a year, and his service on a NATO subcommittee brought him to many foreign countries. When the children were sufficiently independent, Adina accompanied him, and they had fascinating experiences traveling in Europe, Asia, and the former Soviet Union.  They also made a regular practice of taking their children's families to warm places south of the U.S. border.

Eli and Adina began to share their time between Cleveland and Denver, where his two eldest daughters had settled, in 1997, and then moved to Denver in 2003. Once they gave up living in Cleveland, they switched to living part-time in Portland, OR, where their youngest daughter resides.

After moving to Denver, Eli and Adina joined B'nai Havurah and enjoyed membership in Havurah Bentzion. Eli participated in many activities at B'nai Havurah; he contributed to several different liturgy projects and was a constant presence in Pat Madsen's course "The Rest of the Tanach." Eli was a devoted fan of the Colorado Symphony Orchestra and took 6-9 OLLIE classes per year. He and Adina hiked and explored the mountains until he was in his 80’s. Eli played recorder on his own and at Swallow Hill until his hands could no longer do what he told them to. He did many of the word and Sudoku puzzles in two different newspapers up until the morning before he died; he was sharp and had full cognition until his last breath.

Eli and Adina were greatly attached to family and turned many close friends into family.  Numerous cousins, nieces and nephews, colleagues, and friends of all generations mourn his passing. He is survived by his children, Deborah (Philip Hiester) Reshotko, Naomi (PB Schechter) Reshotko, and Miriam (Lee Gordon) Reshotko, and grandchildren Sasha Reschechtko, Amit (Haley) Gordon, Yevanit Reschechtko, Nadav Gordon, and Maia Gordon, and his sister-in-law, Paula Reshotko. He led a wonderful and long life, but it was his great sorrow to outlive so many who were beloved and younger, including his wife, Adina, his brother, Meyer, and two cousins with whom he grew up as siblings, Goldie Nesenoff and Debbie Kaufman. He was also very close to his sister and brother-in-law, Shirley and Jerry Anger, of blessed memory.

Eli will be missed greatly by all of his communities, both personal and professional.  His long, exemplary life and body of work will continue to inspire generations to come.

Service, Tuesday, December 9th, Feldman Mortuary Chapel, 9:30 AM; Livestream on the Feldman Mortuary YouTube channel; Interment at Golden Hill Cemetery.
