Bergström's inequality remains a foundational element in modern probability theory, cementing the legacy of a scholar who spanned the academic landscape of twentieth-century Sweden. Born in 1908 in Mölltorp, this mathematician dedicated his career to advancing the understanding of central limit theorems and the intricate structures governing stable distribution functions throughout a lifelong commitment to rigorous inquiry.
Early Academic Formation
Harald Bergström began his formal studies at Uppsala University, where he engaged with mathematics, physics, and chemistry. He earned his master's degree in 1931. Following a brief period teaching in secondary schools between 1932 and 1934, he returned to Uppsala to serve as a research assistant. He completed his Ph.D. in 1938 and continued to teach at the institution until 1945. During these formative years, his scholarship primarily addressed algebraic number fields.

Take the IQ test →Transition to Chalmers University
In 1946, he relocated to the Chalmers University of Technology in Gothenburg. His professional scope widened significantly there, leading to his appointment as professor of applied mathematics in 1949. By 1960, the university expanded his faculty responsibilities to include professorships in numerical analysis and mathematical statistics. He remained active in this capacity until his retirement as professor emeritus in 1974.
Contributions to Probability
Upon moving to Chalmers, his research focus shifted toward probability theory and statistics. He developed critical insights into central limit theorems and the theory of alpha stable distributions. His influence extended to the next generation of scholars as he served as the supervisor for Peter Jagers. His stature in the field was marked by invitations to speak at the International Congress of Mathematicians in Oslo in 1936 and Cambridge, Massachusetts, in 1950. In 1973, Chalmers University issued a collection of essays to honor his sixty-fifth birthday.
Major Publications
His written contributions include two significant books: 'Limit Theorems for Convolutions', published in 1963, and 'Weak Convergence of Measures', released in 1982. Throughout his career, he authored numerous articles in journals such as the 'Scandinavian Actuarial Journal' and 'Arkiv för matematik'. These works spanned from his 1937 dissertation on biquadratic number fields to later research on the convergence of random variables.
