Nils was born into the noble Segerstråle family in Turku, Finland, on 31 May 1893. He was the son of vice district judge (vice häradshövding) Georg Segerstråle and his wife, Karin Tawaststierna. His brothers were military officer and business executive Torsten Segerstråle [sv] (1889–1946) and lawyer Carl-Georg Segerstråle [sv] (1900–1988). He was a cousin of painter and graphic artist Lennart Segerstråle and writer and teacher Solveig von Schoultz.

While serving in the military, Segerstråle was commissioned as a underlöjtnant in the Göta Life Guards (I 2) in 1914 and promoted to lieutenant in 1917 and captain in 1929. He served as a military attaché in Helsinki from 1920 to 1922 and as an adjutant at the Swedish Infantry Gunnery School from 1924 to 1925.

Throughout his lifetime, he published several notable works, including Hamiltonian Castles and Manors of Sweden (1976) and Swedish Entitled Estates (1979).
