Lilian Heath (December 29, 1865 – August 5, 1962) was the first woman physician in the state of Wyoming and one of the first to practice medicine west of the Mississippi River.

She is notorious for having used the top of the skull of outlaw Big Nose George Parrott as a doorstop and pen jar.

[4] She observed the solar eclipse of July 29, 1878, along with scientist Henry Draper and inventor Thomas Edison, who had come to Wyoming to conduct experiments and had stayed in the Rawlins House, where the Heaths were living at the time.

In the early 1880s, Heath's father obtained a job for her as an assistant to Thomas Maghee, a physician employed by the Union Pacific Railroad.

[8] She kept the skull cap for decades and it was positively identified as an exact match in the 1950s after the remainder of Parrott's body was exhumed and examined.

[3][5][9] She enrolled in the University of Colorado at Boulder for a year, and then transferred to the College of Physicians and Surgeons in Keokuk, Iowa, where she was one of three women in the entering class of 22 students.
