|PAUL LANGEVIN (1872-1946)|
23 January 2022 marks the 150th anniversary of the birth of Paul Langevin, the eminent French physicist who is the father of pulse-echo ultrasound. During 1917, working with the French and British Navies, he designed the first piezoelectric ultrasonic transducers using X-cut quartz. These were operated in pulse-echo mode to detect submarines. Subsequent developments in ultrasound, including its diagnostic, therapeutic and surgical uses, all derive from Langevin’s pioneering work during WWI. Several publications and events are being planned during 2022 to mark his anniversary.

X-RAYS TO EXILE: ARTHUR SCHÜLLER
Schüller was born in 1874 and the arc of his life mirrored the rise and decline of Austria from 1870 till 1955. The Schüller family origins lie in Bucovice and Brunn but his early medical career was spent in Berlin and at the AKH in Vienna.
In 1906 he married Margarete Stiassni, daughter of a wealthy Brunn industrialist. In spite of severe financial constraints on the Medical School after World War I , Arthur was closely involved in the successful graduate courses for foreign doctors who came to learn from those who had been leading figures in establishing Vienna’s pre-
As a Jew he was expelled from the University in 1938. His search for a home elsewhere involved fellow scholars in the USA, UK and Australia . After a spell in Oxford he settled in Australia with eventually at post at St Vincent’s Hospital in Melbourne.
The Schüllers’ two sons had died in Nazi camps and this appears to have provoked Arthur's later decline into withdrawal and depression. He and Margarete lived in Heidelberg, a suburb of Melbourne, until his death in 1957.
