Royden is the author of a popular textbook on After study at Phoenix College, Royden transferred in 1946 to Stanford University, where he received his bachelor"s degree in 1948 and his master"s degree in 1949 with a master"s thesis written under the supervision of Donald Spencer. At Stanford University he became an assistant professor in 1951, an associate professor in 1953, and a full professor in 1958. In addition to serving on the faculty of the mathematics department, for Stanford"s School of Humanities and Sciences he was in 1962–1965 associate dean, in 1968–1969 executive dean (acting dean until the vacancy was resolved), and in 1973–1981 dean
In 1981 he resigned as dean to work full-time as a mathematics professor
He was on the editorial board of the Pacific Journal of Mathematics for the five years from 1956 to 1960. Royden was a Visiting Scholar at the Institute for Advanced Study in Princeton for 3 months in the fall of 1969, 3 months in the spring of 1974, and for the academic year 1982–1983.
In 1970 he showed the equivalence of the Kobayashi metric and the Teichmüller metric on Teichmüller space. Royden was a Guggenheim Fellow for the academic year 1973–1974.
In 1974 he was an Invited Speaker (Intrinsic metrics on Teichmüller space) at the International Mathematical Congress in Vancouver.
His doctoral students include Peter A. Loeb and John Wetzel. R. 43. 43. 90. 2.
