What president named Yosemite as a National Park?

Answer 1

On June 30, 1864, President Abraham Lincoln signed a bill granting Yosemite Valley and the Mariposa Grove of Giant Sequoias to the State of California as an inalienable public trust. This was the first time in history that a federal government had set aside scenic lands simply to protect them and to allow for their enjoyment by all people. This idea was the spark that allowed for Yellowstone becoming the first official national park a few years later, in 1872.
