Lars Gunnar Edvard Nilson (28 September 1872 – 28 March 1951) was a Swedish physician. Westermark served as Surgeon-in-Chief of the Swedish Navy and head of the Swedish Naval Medical Officers' Corps from 1917 to 1937.

Early life
Nilson was born on 28 September 1872 in Uppsala, Sweden, the son of Professor Lars Fredrik Nilson and his wife Alva Forssman. He passed mogenhetsexamen in 1890. He received a Bachelor of Medical Sciences degree from Uppsala University in 1895 and he performed study trips in Belgium, England, France, the Netherlands, Germany and Austria. Nilson was a doctor exhibitioner in the Swedish Navy from 1898 to 1902 and received a Licentiate of Medicine degree at Karolinska Institute in Stockholm in 1899.

Career
After several medical employments, including from 1900 to 1903 at Maria Hospital in Stockholm, Nilson became naval surgeon of the 2nd class in the reserve in 1903 and served as naval surgeon of the 1st class and hospital doctor in the surgical department at the Navy's Hospital in Karlskrona from 1903 to 1917, whereby he planned and led its rebuilding from 1906 to 1911. Nilson received a Doctor of Medicine degree from Lund University in 1911 and was appointed first naval surgeon in the Swedish Naval Medical Officers' Corps in 1916. Nilson served as Surgeon-in-Chief of the Swedish Navy and head of the Swedish Naval Medical Officers' Corps as well as head of the Royal Swedish Naval Materiel Administration's Sanitation Department from 1917 to 1937.

In addition, he was from 1919 to 1940 the chief physician in the insurance company Lifförsäkrings-aktiebolaget De förenade and chief physician at the Reservespital XV in Vienna in 1916 and the Swedish government representative at the International Red Cross Conferences in Geneva in 1925 and in The Hague in 1928 as well as at the International Congress of Military Medicine and Pharmacy in London in 1929. Among his assignments it may also be mentioned that he was chairman of experts regarding the employment of military doctors at civilian hospitals in 1918 and regarding new regulations for the navy in 1927, board member of the Swedish Insurance Association (Svenska försäkringsföreningen) from 1922 to 1933 and a member of the Executive Board for Allmänna Änke- och Pupillkassan from 1926. He was secretary of the Swedish Medical Society from 1919 to 1940 and in the latter year became an honorary member there.

Nilson acted emphatically against the questionable merger of the army and navy healthcare system. Among other things, he promoted the application of ophthalmology in the navy and took an interest in the medical aspects of the naval air force. Nilson's approximately fifty writings in naval-hygienic, surgical and scholarly-historical subjects includes Sjökrigets kirurgi (1913), Marinens hälso- och sjukvård (1924; 2nd edition 1930), Hälso- och sjukvård till sjöss (1938), Berömda svenska läkare (1945) och Svenska läkaresällskapet 1908—1938 (1947, a continuation of the society's centenary history).
