Dr Harris Peyton Mosher gave his lecture in 1929 and used his lecture to speak on a number of recent discoveries. Firstly, he looked at the anatomy of the lower oesophagus and how understanding had changed using dissection, microscopy and radiography. He went on to speak about the pioneering use of barium to find a fluid level in the oesophagus and finally of seidlitz powder in creating gas bubbles to increase visibility.
Harris Mosher was born in 1867 in Maine, America. From the start of his schooling, he went from strength to strength and became the first professor of laryngology and otology at Harvard, the first time these subjects had had a dedicated professor teaching these subjects full time in America. His success culminated in his Presidency of all Otolaryngologic Societies in America, among numerous other awards.
