In 1903, the Yankee steam-powered car inventor Freelan Oscar Stanley (1849-1940) was stricken with a life-threatening resurgence of tuberculosis. The most highly recommended treatment of the day was fresh, dry air with lots of sunlight and a hearty diet. Therefore, like many "lungers" of his day, Stanley resolved to take the curative air of the Rocky Mountains. He and Flora arrived in Denver, Colorado in March and, in June, on the recommendation of Dr. Sherman Grant Bonney, relocated to Estes Park, Colorado for the rest of the summer. Over the course of the season, Stanley's health improved dramatically. Impressed by the beauty of the valley and grateful for his recovery, he decided to return every year. He lived to the ripe age of 91, dying of a heart attack in Newton, Massachusetts, one year after his wife, in 1940.
