The Navy Distinguished Service Medal is a military decoration of the United States Navy and United States Marine Corps which was first created in 1919 and is presented to sailors and marines to recognize distinguished and exceptionally meritorious service to the United States while serving in a duty or position of great responsibility.
The 66th United States Congress was a meeting of the legislative branch of the United States federal government, comprising the United States Senate and the United States House of Representatives. It met in Washington, D.C., from March 4, 1919, to March 4, 1921, during the last two years of Woodrow Wilson's presidency. The apportionment of seats in the House of Representatives was based on the 1910 United States census.
