📌 Executive Profile & Vital Statistics
1. Presidential Pedigree, Indiana Lawyer & Civil War Brigadier General
Benjamin Harrison was born on August 20, 1833, in North Bend, Ohio, possessing the most illustrious political pedigree in American history: he was the grandson of 9th President William Henry Harrison and the great-grandson of Founding Father Benjamin Harrison V. Graduating from Miami University (Ohio) in 1852, Harrison established a prominent law firm in Indianapolis, Indiana.
During the Civil War, Harrison raised the 70th Indiana Infantry, serving with distinction under General William Tecumseh Sherman. Promoted to Brigadier General for heroic leadership at the Battle of Peach Tree Creek (1864), Harrison returned to Indiana, serving as US Senator (1881–1887) where he championed pensions for Union veterans and Native American education.
3. The Sherman Antitrust Act (1890): Banning Corporate Monopolies
Harrison's administration presided over one of the most productive legislative sessions in American history. On July 2, 1890, President Harrison signed the historic Sherman Antitrust Act, authored by Senator John Sherman.
As the first federal statute prohibiting monopolistic trusts, price-fixing, and business combinations in restraint of trade, the Sherman Antitrust Act provided the permanent statutory foundation for all future progressive trust-busting under Theodore Roosevelt and William Howard Taft.

On March 3, 1891, Harrison signed the Forest Reserve Act of 1891. Utilizing its Section 24, Harrison unilaterally set aside over 13 million acres of public land as federal forest reserves, including the Yellowstone National Park Timberland Reserve, laying the cornerstone of American environmental conservation.
