The Euler–Maruyama method for the numerical solution of stochastic differential equations bears his name. Maruyama was born in 1916 and graduated from Tohoku University, where he studied Fourier analysis and physics. He began his mathematical work with a paper on Fourier analysis in 1939. He became interested in probability theory through the study of Norbert Wiener's work. He was appointed Assistant professor at the Kyushu University in 1941. When Kiyosi Itô published his papers on stochastic differential equations in 1942, Maruyama immediately recognized the importance of this work and soon published a series of papers on stochastic differential equations and Markov processes. Maruyama is known in particular for his 1955 study of the convergence properties of the finite-difference approximations for the numerical solution of stochastic differential equations, now known as the Euler–Maruyama method. In harmonic analysis, he studied the ergodicity and mixing properties of stationary stochastic processes in terms of their spectral properties. Maruyama also studied quasi-invariance properties of the Wiener measure, extending previous work by Cameron and Martin to diffusion processes.

He commanded the fleet from 1939 until his death in 1943, overseeing the start of the Pacific War in 1941 and Japan's initial successes and defeats before his plane was shot down by U.S. fighter aircraft over New Guinea. Yamamoto graduated from the Imperial Naval Academy in 1904 and served in the Russo-Japanese War, where he lost two fingers at the Battle of Tsushima. He later studied at Harvard University in the United States and was appointed naval attaché to the Japanese embassy in Washington. His experiences convinced him that naval power depended on access to oil and industrial capacity, and that Japan thus had little hope to defeat the U.S. in a war. He was one of the first naval leaders to conclude that naval aviation and aircraft carriers would play a decisive role in any future conflict. In 1936, Yamamoto was appointed navy vice minister, and opposed Japan's alliance with Germany and Italy in the Tripartite Pact of 1940. In 1939, he was appointed commander-in-chief of the Combined Fleet, and was tasked with creating a strategy for war with the United States; Yamamoto favored a surprise attack, which was carried out at the start of the war with an attack on Pearl Harbor in December 1941. In the early months of the war, the Japanese fleet scored a series of decisive naval victories. These gains were halted at the Battle of Midway in June 1942, in which four Japanese carriers were sunk. Yamamoto committed to the defense of the Solomon Islands in the Guadalcanal campaign, but was unable to prevent their capture. In April 1943, Yamamoto was killed after American code breakers intercepted his flight plans, enabling the United States Army Air Forces to shoot down his aircraft.
