Theodore Roosevelt

On October 27, 1858, in New York City, Theodore Roosevelt Jr. was born into privilege but also into a sickly body that suffered from severe asthma. His wealthy father told young “Teedie” that he must build his body through his own will, advice that shaped a philosophy of “the strenuous life” that would define his character and presidency.

Despite his physical challenges, Theodore’s intellectual appetite was voracious. He was a Harvard-educated naturalist who published his first book on birds at nineteen, a historian whose “The Naval War of 1812” became a classic, and a rancher who learned grit in the Dakota Badlands after losing his wife and mother on the same devastating day in 1884.

Roosevelt’s political rise was meteoric. At twenty-three, he became the youngest person ever elected to the New York State Assembly. As Police Commissioner of New York City, he fought corruption by patrolling the streets personally at midnight. As Assistant Secretary of the Navy, he prepared for the Spanish-American War, then famously led his “Rough Riders” cavalry regiment in the charge up San Juan Hill, becoming a national hero.

The assassination of President William McKinley in 1901 thrust Roosevelt into the presidency at age forty-two, making him the youngest person ever to hold the office. He brought unprecedented energy and reformist zeal to the White House, promising Americans a “Square Deal” that would control corporate power while protecting workers and consumers.

Roosevelt’s domestic agenda embodied the rise of democracy through progressive reforms. He became the first president to take on the powerful trusts, earning the nickname “Trust Buster” for breaking up monopolies. He championed pure food and drug laws, established national parks and forests, and mediated labor disputes with an even hand that respected both workers and business owners.

In foreign policy, Roosevelt projected American power with his philosophy of “speak softly and carry a big stick.” He orchestrated the construction of the Panama Canal, mediated the Russo-Japanese War (earning the Nobel Peace Prize), and established the Roosevelt Corollary to the Monroe Doctrine, asserting America’s role as a global police power.

Conservation became Roosevelt’s greatest passion and most lasting legacy. He set aside over 230 million acres of public land, created five national parks, eighteen national monuments, and 150 national forests. He understood that preserving America’s natural heritage was essential for future generations and that wise use of resources was a patriotic duty.

After leaving the presidency in 1909, Roosevelt grew dissatisfied with his successor, William Howard Taft. In 1912, he formed the Progressive “Bull Moose” Party and ran for an unprecedented third term. Though he lost to Woodrow Wilson, his campaign demonstrated the continuing appeal of progressive ideals and his own irrepressible energy—even after being shot during a campaign speech, he insisted on finishing his remarks before seeking medical attention.

Roosevelt’s final years were marked by personal tragedy when his youngest son Quentin was killed in World War I, and by his own declining health from diseases contracted during his 1913-1914 expedition to explore Brazil’s River of Doubt. He died in his sleep on January 6, 1919, at Sagamore Hill, his beloved Long Island home.

Theodore Roosevelt transformed the American presidency from a largely ceremonial office into the dynamic center of national life. He proved that government could be a force for justice and progress, that America could lead on the world stage while preserving its democratic values, and that one person’s energy and conviction could inspire a nation to greatness.

His image on Mount Rushmore stands alongside Washington, Jefferson, and Lincoln—a fitting tribute to the president who expanded American democracy and established the country as a progressive force in the modern world.
