Has an IEEE Organizational Unit agreed to arrange the dedication ceremony? Yes
Has the IEEE Section in which the milestone is located agreed to take responsibility for the plaque after it is dedicated? Yes
Has the owner of the site agreed to have it designated as an Electrical Engineering Milestone? Yes
Year or range of years in which the achievement occurred:
Title of the proposed milestone:
Paul Langevin's Improvements to Sonar, 1917
Plaque citation summarizing the achievement and its significance:
In France in 1917, Paul Langevin, a French physicist, produced transceivers using the piezo-electric effect of quartz crystals, and designed a submarine detector based on the effect, resulting in an improved method for submarine ultrasonic echo detection, namely sonar, obtaining 4000 meter echo soundings from the cable ship CHARENTE in the Bay of Biscay. Echo sounding based on piezoelectric effect became a central topic for new researchers, academic physicists and electrical engineers, with many applications like medical echography and diverse acoustic sensors. Langevin’s extensive knowledge of and practice with piezoelectricity beneficiating from research of Pierre Curie, which allowed him to manipulate the crystals and contrive the novel ultrasonic design required

Street address(es) and GPS coordinates of the intended milestone plaque site(s):
THe Langevin Institute 1 rue Jussieu, 75238 Paris Cedex 05, France http://www.institut-langevin.espci.fr/the_langevin_institute?lang=en
Describe briefly the intended site(s) of the milestone plaque(s). The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque.
Please give the address(es) of the plaque site(s) (GPS coordinates if you have them). Also please give the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. If visitors to the plaque site will need to go through security, or make an appointment, please give the contact information visitors will need. Historic site. Paul Langevin was Professor at ESPCI that host the Langevin Institute. Sonar has been invented in ESPCI (Ecole Superieure de Physique Chimie) in Paris (http://www.espci.fr/en/)
Are the original buildings extant?
New extant hosting "The Langevin Institute". The Langevin Institute is an extend of ESPCI
Details of the plaque mounting:
Entrance Hall of the Langevin Institute.
How is the site protected/secured, and in what ways is it accessible to the public?
All visitors have access to Entrance Hall of the Langevin Institute
Who is the present owner of the site(s)?
What is the historical significance of the work (its technological, scientific, or social importance)?
See attached document. Many applications in civil (echography, ...) and military domains (sonar)
What obstacles (technical, political, geographic) needed to be overcome?
Technical issue: control of piezo-electric Quartz transducer
What features set this work apart from similar achievements?
