June 25 in business history: barbed wire, the labor floor, the march that forced a president's hand, and the paper that made 12,000 millionaires
On June 25, 1867, Lucien B. Smith filed the first U.S. barbed wire patent — a concept that became the invention that privatized the American West. On June 25, 1938, FDR signed the Fair Labor Standards Act on a Saturday alone, establishing a 25-cent minimum wage covering one-fifth of the labor force — a compromise framework expanded eight more times over the following decades. On June 25, 1941, he signed Executive Order 8802, the first federal civil rights executive order since Reconstruction, six days before a threatened 100,000-person march forced his hand. And on June 25, 1981, Microsoft incorporated in Washington state — the governance restructuring that created the equity mechanism behind one of history's most consequential technology companies.
