Almost in babyhood Teddy began to read. His sister tells how he came to her one day, still wearing a stiff white dress and his curly hair long, dragging a book that was too big to carry in his little arms, to ask her what “foraging ants” were. While learning to walk, ride horseback, and swim, Theodore Roosevelt was reading books and finding out all he could about birds, butterflies, and other insects by watching and catching them. He and several other small boys at Oyster Bay, where the family spent many summers, collected and mounted specimens, and started what the boys called the “Roosevelt Museum of Natural History.”

While preparing a butterfly for his “museum,” Theodore happened to look at it through a small glass and found that he could not see as well as other boys. His father had spectacles fitted to his eyes, and everything looked so much clearer and brighter that he went about laughing and shouting “I can see!—I can see!

The year when Theodore was eleven, the family traveled in Europe and Egypt. During their trip up the Nile he made quite a collection of the bright birds of that country for his “museum.” His brother scolded because Theodore kept live specimens and mounting materials in the washbowls and pitchers in the rooms of the hotels where they were staying. The boys lived and studied in Germany long enough for Theodore to learn to speak German quite well.

At sixteen, young Roosevelt went to Harvard University. He was a good student, yet he spent much of his time in athletic sports. He would tie his glasses tight to his head and box with the biggest fellows he could find who would fight with him. Of these “misfit matches” the other students said, “Roosevelt has a bad handicap, but what he lacks in size and strength he makes up in pluck.”

He spent his college vacations in the backwoods of Maine, and when he was graduated, at twenty-one, he had not only shown himself to be a good student, but he had gained much in health and strength. Also he read much more than was required in his college studies, and had begun to write his first big book, “The History of the Naval War of 1812.”

After graduation, Theodore began to study law, and decided to go into politics. Many of the ward headquarters of New York City were in saloons. As he went about with the ward workers, they expected their “silk stocking” candidate, as they called young Roosevelt, to favor the saloons and to use his “roll” (of money) freely. But instead of this, Theodore Roosevelt told them plainly that, if elected, he would fight against them and their bad methods.

He was elected and he kept his word. He began as a reformer, exposing and opposing bribery and other wicked things that were being carried on in politics. As Police Commissioner of New York he found much that was wrong and fought and struggled to make it right. He was Assistant Secretary of the Navy when the war was declared against Spain. He could not rest day or night because he found so much to do in getting ready to carry on the war. It was he who sent the word to Admiral Dewey on the other side of the world which prepared him for battle and helped the United States with the famous victory of Manila Bay. He was so keen and active that President McKinley said to his Cabinet: “Roosevelt has the whole program of the war mapped out.” But he resigned from his office to become a colonel of the Rough Riders, and was soon leading his brave company of cowboys and college men up San Juan Hill in the face of a blazing Spanish battery.

Although Colonel Roosevelt was by no means highest in military rank, he became the hero of the United States’ war with Spain. When that war was over he was elected governor of New York. All the “bosses” hated this man who would not consent to their robbing or cheating the people. They asked him to run for Vice-President of the United States, thinking that his hands would be tied, for a vice-president has very little to say as to how the government shall be conducted. But in a few months President McKinley, with whom Roosevelt was elected Vice-President, was shot and killed. This made Theodore Roosevelt President of the United States. Four years later he was elected President again. His courageous spirit and true heart, with his active brain and tireless body, made him one of the greatest presidents of the United States.

He had kept himself in good health and spirits by his constant labors and many risks as a cowboy on his own ranches, and by hunting grizzly bears and other big game in the Far West. Even while living in the White House, he showed his friends and fellow-workers in the government what he meant by “the strenuous life.”

Many expressions first used by Theodore Roosevelt are now heard in common conversation. This is the first use he made of the words, “the strenuous life”:
