Labor Day 1911 in Medford, Oregon

While most sources, even the Department of Labor, credit Peter McGuire with
the origination of Labor Day (1882), recent evidence suggests that the true
father of Labor Day may in fact be another famous union leader of the 19th
Century, Matthew Maguire.

Oregon was the first state to make it a holiday on February 21, 1887. By the
time it became a federal holiday in 1894, thirty states officially celebrated
Labor Day.
