Theodore “Teddy” Roosevelt, the 26th president of our country, was indeed an amazing man, and more than 100 years after his two terms as president, we can still find things in his life’s work that have an impact on our own world.

An assortment of “T.R.” memorabilia is on display at the Leland Stanford Mansion State Historic Park. The exhibit is entitled “The Great Dreamer and the Great Doer: Theodore Roosevelt’s Impassioned Life,” and covers the most important parts of Roosevelt’s career, especially those pertaining to his conservation efforts.

“We owe Roosevelt so much in the way of conservation,” Adam Gottlieb, 46, said. “For the bird sanctuaries that he created, the national park lands that he created. It is without peer.”

Gottlieb’s personal collection of T.R. memorabilia makes up the exhibit, and he has been gathering the artifacts since he was 10 years old. He’s built up quite a collection in that time.

“I was convinced that this man was larger than life,” he said, remembering the first time he visited Roosevelt’s summer home, Sagamore Hill. “He was a big game hunter, he was a Rough Rider, he was a governor. Theodore Roosevelt lived life large.”

The exhibit includes rare, original “teddy bears,” promotional buttons and pins and many other artifacts from T..R.’s time as governor and president.

Included alongside the memorabilia are wonderful posters that highlight the conservational efforts of T.R. They are produced by the California Department of Parks and Recreation.

“The books he read taught him about conservation,” Park Interpretive Specialist Debbie Hollingsworth said. “That forests are not evil, scary places, but places to be revered.”

The exhibit runs through June 2011 and is free to the public. For information visit here.
