Early life and career
Ross was born Arnold Ephraim Chaimovich[1] on August 24, 1906, in Chicago to Ukrainian-Jewish immigrants.[2] He was an only child.[1] His mother supported the family as a physical therapist.[1] Ross returned to Odesa, Ukraine with his mother in 1909 for assistance from her extended family,[1] and stayed once World War I and the Russian Revolution broke out.[2] The two events led to widespread famine and economic woe in the region.[1] Ross learned Russian at the behest of his mother, and developed a love of the theater and language.[1] Ross's mother encouraged him to read, which he did often, and subscribed to a private library since Odesa had no public library.[1] He credited his favorite uncle, an X-ray diagnostician, with introducing him to mathematics.[1] The uncle had hired Samuil Shatunovsky to tutor his talented son, and Ross asked to join in.[1] As money meant little due to inflation, Shatunovsky was paid to tutor the two boys with a pound of French hard candy.[1] During this time, Ross was not taught with textbooks or lectured on geometric proofs.[1] His geometry teacher would ask the class to prove and justify ideas on the blackboard per trial and error.[1] Many universities were closed due to the famine, but Odesa University reopened and let a small group of adolescents attend, including Ross.[1]
In Moore's teaching style, he would propose a conjecture and task the students with proving it.[1] Students could respond with counter-conjectures that they would defend.[1] Ross found Moore's method exciting,[1] and his pedagogy influenced Ross's own.[2] Ross graduated with a B.S. degree[4] and continued his study as Leonard Eugene Dickson's research assistant.[2] Ross earned a M.S. degree[4] and finished his Ph.D. in number theory at the University of Chicago in 1931 with Dickson as his adviser.[2] Ross's dissertation was entitled "On Representation of Integers by Indefinite Ternary Quadratic Forms".[1] He did not pay tuition after his first quarter, which he credits to Dickson.[1]
Ross married Bertha (Bee) Halley Horecker, a singer-musician and daughter of Ross's Chicago neighbors, in 1931,
Ross Mathematics Program
While at Notre Dame in 1947, Ross began a mathematics program that prioritized what he described as "the act of personal discovery through observation and experimentation" for high school and junior college teachers.
This emphasis on computation alone too often produces students who have never practiced thinking for themselves, who have never asked why things work the way they do, who are not prepared to lead the way to future scientific innovation. It is precisely this independence of thought and questioning attitude that the Ross Program strives to nurture.
Ross Program brochure[8]
The program usually has 40–50 first-year students, 15 junior counselors, and 15 counselors.[2] Students are admitted by application—which includes a set of mathematical questions—or by showing "a great eagerness to learn."[2] First-year students meet daily for lectures in elementary number theory and thrice weekly for problem seminars.[2] They are encouraged to think like scientists and devise their own proofs and conjectures to the problems posed,[2] which occupies most of their free time.[8] Ross designed the daily problem sets,[9] and many questions contain his signature directions: "Prove or disprove and salvage if possible."[1] Successful students are asked to return as junior counselors and counselors in future summers.[2] Junior counselors revisit the daily lectures and help first-years with their questions.[2] They also can take advanced courses such as combinatorics[2] and graduate seminars.[9] Student problem sets are graded daily by the live-in counselors.[2]
The program was funded in the 1960s by a National Science Foundation (NSF) program that supported summer programs in science education, but not returning students.[2] As NSF support fluctuates, the program has been funded by various means including gifts from donors, scholarships from businesses, a National Security Agency grant, the university, and its mathematics department.[2] It also receives financial support from the Clay Mathematics Institute.[1][8]
The program grew rapidly with input from prominent mathematicians such as Ram Prakash Bambah, Hans Zassenhaus, Thoralf Skolem, and Max Dehn.[2] In the 1960s and 1970s, Ross brought mathematicians including Zassenhaus, Kurt Mahler, and Dijen K. Ray-Chaudhuri to teach there regularly.[1] Ross left Notre Dame to become chair of Ohio State University's mathematics department in 1963, and the program followed in the 1964 summer.[2] The program briefly moved to the University of Chicago in the summers of 1975–1978 at mathematician Felix Browder's invitation.[2] The program is unadvertised and depends on personal contacts and word of mouth to propagate.[1][2][8] It is recognized by mathematicians as one of the best mathematics programs for high school students.[8]
Admission to the program is competitive, with an approximately 15% acceptance rate. [10]
Retirement and death
Ross reached his mandatory retirement from Ohio State University in 1976,[2] when he became Professor Emeritus,[4] but continued to run the summer program through 2000,[9] after which he had a stroke that left him physically impaired and unable to teach.[1] Daniel Shapiro led the program upon Ross's exit.[1][11] Shapiro was a former counselor at the program.[3]

Ross's wife, Bee, died in 1983 and left Ross in a deep depression.[1] His colleagues said he "lived only for his summer program" in this period.[1] He later met a French widow of a diplomat, Madeleine Green, and they married in 1990.[1]
Ross died on September 25, 2002.[12] Notices of the American Mathematical Society and MAA FOCUS ran memorial articles on Ross.[3][9][12] Mathematicians such as Karl Rubin expressed their personal debts to Ross.[3] He did not have any children.[2][13]
Legacy
Ross's biggest contribution to his field was not through his research, but through his mathematics education programs.[9] He had run each of his summer programs from 1957 to 2000,[9] working with over 2,000 students.[1] His summer program graduates found roles in prestigious research positions in fields across the sciences.[9] The Ross Program was acclaimed by mathematicians as highly influential.[8][9][14]
The Ross Program inspired many similar programs, the closest in likeness being the Program in Mathematics for Young Scientists (PROMYS) at
The Arnold Ross Lecture Series founded in his name in 1993[13] and run by the American Mathematical Society puts mathematicians before high school audiences annually in cities across the United States.[1] Ohio State University organized two reunion-conferences for Ross with program alumni, friends of Ross, and a series of science lectures,[1] in 1996 and 2001.[15]
