Ethelbert Stewart (1857–1936) was the commissioner of the U.S. Bureau of Labor Statistics (BLS) from 1921 to 1932.

[2] In that position he had a public role in how the organization should track women workers, child labor, and occupational injuries and illnesses.

In the fall of 1913 he mediated a coal mining dispute involving the Rockefeller interests in Colorado and helped resolve the Indianapolis streetcar strike of 1913.

It was hard to keep the Bureau staffed during World War I and Stewart advocated offering pensions to civil servants.

[4] When commissioner Royal Meeker left in 1920, Stewart was nominated by President Woodrow Wilson to take the top role, newly elected President Warren Harding re-nominated him, and Stewart was confirmed in 1921.
