An addition will be made to the Faculty of the Engineering School next Monday, when Professor Pierre Lemaire will arrive to take up his duties as exchange professor from France in the field of applied science. This particular exchange has been in effect since 1921, and has proved to be very successful in establishing sympathetic and cordial relations between the French and American Universities. Former French professors who have served in the University are Professors Cavalier and de Margerie.

Professor Lemaire occupies at present the position of Assistant Director of the Ecole Centrale Lyonnaise in France, and he is as well a reserve officer of the French navy. He entered the naval service in 1900 as a sailor but his personal tastes and talents led him to scientific studies. He entered the Ecole Superieur d'Electricite and obtained his degree. After graduating from the school, he received a commission and was detailed to the command of a submarine.

Has Done Scientific Research

After serving for some time in this capacity, Professor Lemaire was detailed to Paris, where he worked on scientific problems. By far the greatest of his accomplishments was his invention of the gyroscope compass, independently of the researches of Sperry, of which he was unaware. While in Paris, Professor Lemaire obtained a degree from the Sorbonne. His researches were soon after recognized and the Academy des Sciences awarded him the Plumey prize, and the Minister of the Navy conferred upon him the Grand Medaille d'Or.

Directed Wireless Station In War

During the war, Professor Lemaire was in charge of the French government wireless station at Bordeaux. He also conducted personally numerous researches on the application of submarine acoustics and made notable discoveries in connection with the effect of sound upon opaque materials, the shape of horns for acoustic instruments, the assembling of receptive membranes and marine microphones, as well as the first oscillographs of propellor vibrations. He is also responsible for an important study of musical acoustics, the significance of which led the French government to commend him and recommend his pursuance of the subject.

Professor Lemaire was called upon during the war to study numerous problems connected with tank warfare, and accomplished the supposedly impossible feat of installing liquid compasses in tanks. His plan for the organization of tank warfare was accepted and put into use by the government.

The first lectures to be given at Harvard by Professor Lemaire will be on Tuesday and Wednesday.
