Maude Abbott
This organizational system was very strong. In fact, she learned so much from comparing different human hearts in the collection that she advanced medical science's understanding of the heart a lot. She first wrote a chapter on congenital heart disease for the book Principles and Practice of Medicine, edited by William Osler. Then she wrote the Atlas of Congenital Heart Disease, a major reference work on the human heart. The American Heart Association published it in 1936, with new editions in 1956 and 2006. This book helped medical scientists understand congenital cardiac problems. It led to treatments for these problems in the second half of the Twentieth century. Abbott was planning a textbook to add to the Atlas. She died before she could write it.
