August and Marie Krogh

August Krogh, the son of a Danish brewer, won the Nobel Prize in 1920 for his discovery of how capillaries open and close in response to oxygen demand by body tissues.

He and his wife, Marie, a physician, worked together, and this biography of two remarkable people beautifully illustrates the intertwining of their personal and professional lives.

It is a book full of human and scientific understanding, written by their daughter who is also a physiologist of stature herself.
