4 November 2021: Joseph Cunningham, author of "New York Power" and expert on the history of the electrification of New York City, will describe how stresses and strains on the electrical grid drove innovative solutions for the generation and distribution of electric power in the metropolis.
On January 15, 1961, a radar tower collapsed into the Atlantic Ocean off the New Jersey coast. All 28 men aboard perished. Known as Texas Tower 4, it monitored the horizon for Soviet bombers as one peg of the North American nuclear defense shield. As the designers of Texas Tower 4 failed to protect their own handlers, how could it be said the emergent American nuclear defense system would protect against an attack that so many feared? In this talk, I examine the construction, everyday life, and ultimate collapse of the tower as well as consider the implications for why a preventable disaster was allowed to occur.

He began his professional career in 1963 as a researcher at INSA, Lyon, where he developed the first European ultrasonic Doppler velocimeter. In 1968, he joined the Faculty of Medicine in Tours, France, where he was assistant, associate, and then full Professor. He also was director of the Group of Public interest GIP “Ultrasound” and of the INSERM research Unit 316. www.inserm.fr
His research activities dealt with ultrasonic instrumentation and clinical applications, and he was principal investigator of several studies in the field of space physiology. In 1972 he and his research group developed one of the first real-time ultrasound imaging systems based on the electronic scanning of a linear array. Pourcelot was also one of the pioneers in clinical Doppler vascular research. In 1974 he described the "Resistance Index" or the "Pourcelot index". In 1977 he described pioneering work on colour-coded Doppler images. He led a team of researchers and clinicians who had devised important and creative experiments in the application of Doppler ultrasound in adult vascular diseases as well as in the assessment of foetal conditions, and designed many innovative apparatuses for the purpose. They were also responsible for important pioneering works on space physiology and medicine (1982-2000), including the first echograph used on board of a space vehicle (1982). Other works included the use of high frequency ultrasound transducers, and techniques in the study of newborn cerebral function, physiology and pathophysiology, and with particular reference to the preterm baby.
Pourcelot co-founded several industrial companies, as well as the French Society for Ultrasound in Medicine and Biology (1972) www.sfaumb.fr, the French Doppler Club (1975) and more recently (2004) the Planiol Foundation www.fondation-planiol.fr He is a member of WFUMB, and was president and member of a large number of learned societies.
In 1995 Pourcelot received the prestigious IEEE Judith A. Resnik Award for his work on ultrasound imaging in the measurement of cardiovascular systems during space flight. In 2003, he was honoured with the Ian Donald Gold Medal for Technical Merit from the International Society of Ultrasound in Obstetrics and Gynaecology (ISUOG).
