Dr. James Tayloe Gwathmey (1863-1944) was a leader in making anesthesiology a highly respected medical specialty. He is best known for writing the first comprehensive American textbook of anesthesia, in 1914. He also invented a range of anesthesia equipment. In 1904, he introduced this mask as one part of a resuscitation apparatus. Gwathmey modified the Esmarch Mask to better fit the contours of the face, and added a tubular rim that is pierced with holes. This can be used to deliver resuscitating oxygen, or a combination of oxygen and anesthetics. When connected to the mask by a hose, these gases flowed through the holes in the rim to be inhaled by the patient. The same concept was further modified a decade later in the Yankauer-Gwathmey Mask.
