Birnbaum, Z. W. (Zygmund William), 1903-2000

Zygmunt William Birnbaum was born in Lwoʹw, Austria-Hungary, in 1903. After obtaining a law degree in 1925 and a Ph. D. in mathematics in 1929, both from the University of Lwoʹw, Birnbaum pursued postdoctural studies at the University of Göttingen in Germany, 1929-1931. Due to worsening economic and political conditions in Germany, Birnbaum worked in New York as a newspaper correspondent and then accepted a research assistantship in biometrics at New York University. In 1939, he joined the University of Washington Department of Mathematics, beginning a distinguished career that extended well beyond his university retirement in 1974. In Seattle, Birnbaum met and married Hilde Merzbach while both of them were involved in assisting Jewish refugees arriving from Europe. These included his cousins, Rita and Jakob Berger, but despite exhaustive efforts, he could not rescue his mother, father, and sister, who eventually perished in Auschwitz. Birnbaum did, however, bring, among others, several talented scientists to the U.S. He also corresponded with another good friend from Lwoʹw, Ala Manelska, who survived six years in a Siberian prison. Birnbaum's academic contributions included teaching and service as well as research and publishing in mathematics and statistics. Among other awards, he received the prestigious S.S. Wilks Medal of the American Statistical Association, and he fought segregation at Institute of Mathematics Statistics meetings. Birnbaum was an outdoor enthusiast in his earlier Seattle years. He died in December, 2000.

Professor of mathematics, University of Washington.

Zygmunt William "Bill" Birnbaum (1903-2000), professor of mathematics and statistics at the University of Washington, 1939-1974, was born in Lwów, Austria-Hungary, 1903, to Ignacy and Lina Birnbaum. He obtained a master of law degree in 1925 and a teaching certificate in mathematics in 1926. Birnbaum taught from 1925 to 1929, when he received his Ph. D. in mathematics. In Göttingen, Germany, a center of world mathematics at the time, Birnbaum continued his mathematical studies and also earned an actuarial certificate. After working for the Phoenix Life Insurance Company in Vienna and Lwów, he secured work in New York with assistance from his relative, Ludwik Rubel, and in 1939, he began a 35-year career in the University of Washington Dept. of Mathematics. In Seattle he met his future wife, Hilde Merzbach, while both of them were assisting Jewish refugees arriving from Europe, but Birnbaum was unable to rescue his mother, father, and sister, who were taken prisoner by the Germans and eventually perished in Auschwitz. Birnbaum's research interests included statistics and computation, and he did pioneering work in reliability and life testing. He was an active member of the Institute of Mathematical Statistics, advocating for meetings to be held on a non-segregated basis. His testimony was cited in the U.S. Supreme Court's decision on the 1962-63 Loyalty Oath suit (Baggett v. Bullitt). Birnbaum received a number of prestigious honors and awards during his career; he died in 2000.

Zygmunt William “Bill” Birnbaum (1903-2000), was for thirty-five years professor of mathematics and statistics at the University of Washington (1939-1974).

Zygmunt William Birnbaum was born in Lwów, Austria-Hungary, on October 18, 1903, to Ignacy and Lina Birnbaum. He attended grade and high schools (gymnasium) in Lwów and Vienna, and then, in deference to his family's wishes that he pursue a "practical" degree, he obtained a master of law degree from the University of Lwów in 1925. He practiced law for a year, but during that time he resumed his studies in mathematics. In 1926 Birnbaum received a teaching certificate in mathematics. He taught at a gymnasium in Lwów from 1925 to 1929 while continuing his graduate studies in mathematics under Hugo Steinhaus and Stefan Banach, among others. He received his Ph.D. in 1929, with Steinhaus as his major professor.

After receiving his Ph.D., Birnbaum went directly to Göttingen, Germany, to continue his studies. Göttingen was central to world mathematics at that time, with such luminaries as David Hilbert, Edmund Landau, Richard Courant, Emmy Noether, and Felix Bernstein, among others, in residence. The city attracted many famous visitors, including Kolmogorov, Alexandrov, and von Mises, during 1929-31, when Birnbaum was there. It was during this time that political events began to portend an uncertain future for Germany generally and academic opportunities for Dr. Birnbaum in particular. Thus it was that he, following advice from Edmund Landau, completed a program leading to an actuarial certificate from Göttingen University's Institute of Insurance Mathematics, then headed by the mathematician-cum-biometrician, Felix Bernstein. In 1931 this permitted him to obtain a position as a life insurance actuary for the Phoenix Life Insurance Company in Vienna and a year later to return to Lwów as chief actuary at the company's Polish subsidiary.

After the Phoenix company went bankrupt in 1936, due in great part to the worsening economic and political conditions in Germany, Dr. Birnbaum decided to try to emigrate to the U.S.A. Although the quotas were full for years to come, he was able to secure employment as a foreign correspondent for a major Polish newspaper. This enabled him to go to New York in June 1937 on a visitor's visa obtained for him by his relative, newspaper editor Ludwik Rubel. During his time in New York, Birnbaum came to know many Central European intellectuals, among them the famed Austrian novelist Hermann Broch, and renewed his friendships with fellow Polish émigré-mathematicians, Mark Kac, Stanislaw Ulam, and others.

Shortly after his arrival in New York, he also met his former Göttingen professor, Felix Bernstein, and accepted from him a research assistantship in biometrics at New York University. His statistical interests and knowledge, which had been kindled during his actuarial studies, grew rapidly under the influence of the leading statisticians at New York and Columbia Universities. In early 1939, Harold Hotelling of Columbia University, a Seattle native with a master's degree in mathematics from the University of Washington, brought to Birnbaum’s attention a position there in the Department of Mathematics. He applied, and supported by letters of recommendation from Courant, Landau, and Albert Einstein, his application was accepted. Thus began his long and distinguished career of over 60 years in the Seattle area, extending well beyond his university retirement in 1974.

Shortly after his arrival in Seattle, Birnbaum met his wife, Hilde Merzbach, while both of them were involved in assisting Jewish refugees arriving from Europe. Birnbaum succeeded in helping many people come to the United States, among them several talented scientists. Despite all of his exhaustive efforts, however, Birnbaum could not rescue his mother, father, and sister before they were taken prisoner by the Germans and transported to Bergen-Belsen. They eventually perished in Auschwitz.

During his long association with the University of Washington, Professor Birnbaum's academic contributions included teaching and service as well as research in the theory and applications of mathematics and statistics. Upon his arrival in Seattle he designed the theoretical courses which formed the basis of one of the first comprehensive undergraduate programs in mathematical statistics in the United States. By 1948 he had founded the Laboratory of Statistical Research which, through its long association with the Office of Naval Research, served to strengthen and expand the graduate and faculty components of these programs.

Professor Birnbaum’s research interests were broad, reflecting the breadth of his early training. He published original material in several areas of mathematics, statistics, and computation and made pioneering studies in reliability and life testing, with important applications in metal fatigue and health statistics. He made significant contributions to complex and functional analysis (including Birnbaum-Orlicz spaces), probabilistic inequalities (e.g. multi-dimensional Chebychev and maximal inequalities), non-parametric and distribution-free statistics (exact, asymptotic, and tabulated distributions), survey non-responses, reliability of complex systems, cumulative damage models, competing risks, survival distributions, and mortality rates.

Birnbaum’s service to his university and professional colleagues, as well as to society at large, went beyond his teaching and research. In 1946 he used his legal and actuarial backgrounds to prepare the legislation that became the statutory basis for the university's retirement system. In 1955 he organized the referendum that resulted in the inclusion of faculty in the social security system. He was responsible for carrying out the 1953 Kingston resolution that all Institute of Mathematical Statistics (IMS) "meetings shall be held on a completely non-segregated basis." He presented the resolution for permanence of this policy at the 1956 Annual IMS meeting held in Seattle. As a plaintiff during 1962-63 in the loyalty oath suit (Baggett v. Bullitt), he was the only witness whose testimony was cited in the U.S. Supreme Court's decision.

In recognition of his many contributions, Z.W. Birnbaum was made a fellow of both the IMS (1949) and the American Statistical Association, and an elected member of the International Statistical Institute. Beginning in 1966 he was editor of the Academic Press monograph series in probability and statistics and was elected president of the IMS in 1964. He was also editor of the Annals of Mathematical Statistics during 1967-70. He received both Fullbright and Guggenheim awards with visiting positions held in Stanford, Rome, Jerusalem, and Paris. In 1984 Birnbaum received the prestigious S.S. Wilks Medal of the ASA for "his theoretical research, wide applications, leadership, inspiration and teaching." He died in December 2000.

Shortly thereafter, he resumed his studies and obtained a Ph.D. in Mathematics in 1929 from the University of Lwów. Dr. Birnbaum then pursued postdoctoral studies at the University of Göttingen in Germany from 1929-1931. It was during this time that political events began to portend an uncertain future for Germany with few academic opportunities for Dr. Birnbaum. He obtained an actuarial certificate from Göttingen and worked as a life insurance actuary, later chief actuary, for the Phoenix Life Insurance Company in both Vienna and Lwów.

After Phoenix Insurance went bankrupt in 1936, due in great part to the worsening economic and political conditions in Germany, Dr. Birnbaum decided to try to emigrate to the United States. Although the quotas were full for years to come, he was able to secure employment as a foreign correspondent for a major Polish newspaper.

Shortly after his arrival in New York, he accepted a research assistantship in biometrics at New York University, where he worked until early 1939, when he was hired by the University of Washington Department of Mathematics. His application was supported by letters of recommendation from Richard Courant, Edmund Landau, and Albert Einstein. Thus began his long and distinguished career of over 60 years in the Seattle area, extending well beyond his university retirement in 1974. Dr. Birnbaum became a naturalized United States citizen in 1943.

In Seattle, Birnbaum met and married Hilde Merzbach while both of them were involved in assisting Jewish refugees arriving from Europe. Throughout World War II, Dr. Birnbaum remained in contact with his cousins and good friends, Rita and Jakob Berger, who had immigrated to England prior to the Soviet occupation of Lwów. Birnbaum assisted the Bergers in immigrating to New York in 1940 and continued to correspond with them for many years. Both Rita and Jakob Berger's families, as well as Birnbaum's parents and sister, were in Lwów during the war. Despite exhaustive efforts, Birnbaum could not rescue his mother, father, and sister before they were taken prisoner by the Germans and transported to Bergen-Belsen. They, along with the Bergers' families, eventually perished in Auschwitz. Birnbaum succeeded, however, in helping others come to the United States, among them several talented scientists. This group included Henry Schaerf in 1946, who was working in Switzerland during the war. Birnbaum also corresponded with another good friend from Lwów who survived World War II, Ala Manelska. Manelska was sent to prison in Siberia by the Soviets for six years after the takeover of Lwów.

During his long association with the University of Washington, Dr. Birnbaum's academic contributions included teaching and service as well as research in the theory and applications of mathematics and statistics. He published original material in several areas of mathematics, statistics, and computation and made pioneering studies in reliability and life testing. Throughout his career and even after his retirement from the University of Washington in 1974, Dr. Birnbaum edited scholarly journals and received Fullbright and Guggenheim awards. He was also awarded the prestigious S.S. Wilks Medal of the American Statistical Association for "his theoretical research, wide applications, leadership, inspiration and teaching."

Dr. Birnbaum's service to his university and professional colleagues, as well as to society at large, went beyond his teaching and research endeavors. He contributed his expertise in organizing the university's retirement system and fought segregation at Institute of Mathematics Statistics meetings. As a plaintiff during 1962-1963 in the Washington State loyalty oath suit (Baggett v. Bullitt), he was the only witness whose testimony was cited in the U.S. Supreme Court's decision.

Dr. Birnbaum was an avid hiker and outdoor enthusiast in his earlier Seattle years. Dr. and Mrs. Birnbaum had two children, Ann Birnbaum, born 1941, and Richard Birnbaum, born 1945. Zygmunt William Birnbaum died in December of 2000.
