This is the second in my Dr. Mary Walker Wednesdays series. Each week I’ll post the first sentence of a new chapter, along with an image that relates to material in the chapter. This week features the man who served as President Lincoln’s first Secretary of War.

Dr. Mary Walker met with sixty-two-year-old Simon Cameron, a tall, clean-shaven man with an abundance of white hair.
