Justin Denzel was an American author of children's and young adult books. He was born in Clifton, New Jersey in 1917. As a child he showed an early interest in nature that was to reappear later in his books. He worked for some years in Alaska, where he wrote for an Alaskan newspaper. He gave up writing after an unsuccessful attempt to write an adult novel, however when he returned to writing he realized he liked to make short stories and children's novels more. Many of his books featured nature and animals and tend to have a historical setting.
I found Dr. Cushing's life to be most interesting. I had previously known of him mainly because his name is associated with a disease I had - Cushing's. This book doesn't talk nearly enough about how he came to discover the causes of Cushing's disease, but I found it to be a valuable resource, anyway. I was so surprised to learn of all the "firsts" Dr. Cushing brought to medicine and the improvements that came about because of him. Dr. Cushing introduced the blood pressure sphygmomanometer to America, and was a pioneer in the use of X-rays.
He even won a Pulitzer Prize. Not for medicine, but for writing the biography of another Doctor (Sir William Osler).
Before his day, nearly all brain tumor patients died. He was able to get the number down to only 5%, unheard of in the early 1900s.
This is a very good book to read if you want to learn more about this most interesting, influential and innovative brain surgeon.
