Question: What is the name of the individual who introduces us to a scientist who is credited with the invention of the first capacitor in 1746?
Context: In the first episode Al-Khalili introduces the history of our understanding of electricity and the harnessing of its power.  He covers the achievements of these "natural philosophers" - Francis Hauksbee, Stephen Gray, Musschenbroek, Benjamin Franklin, Henry Cavendish, Galvani, Volta and Humphry Davy. In physics, charge conservation is the principle that electric charge can neither be created nor destroyed.  The net quantity of electric charge, the amount of positive charge minus the amount of negative charge in the universe, is always "conserved".  Charge conservation was first proposed by British scientist William Watson in 1746 and American statesman and scientist Benjamin Franklin in 1747, although the first convincing proof was given by Michael Faraday in 1843. The Door in the Dragon's Throat is a book in the Cooper Kids Adventure Series by Frank E. Peretti, published in 1985.  The novel introduces us to Dr. Jake Cooper, a Christian archaeologist, and his two children Jay and Lila. "Winners" introduces us to WIN, a project set in place by the Spanish Red Cross in Liberia, with a program to integrate vulnerable women in Monrovia into the social and labor fields.  More than fourteen years of wars have relegated these women to the lowest rung of the social ladder of the already fragile Liberian society, turning them into the perfect victims of a gender violence that could well become an institution. The Chase is a detective novel by author Clive Cussler written in November 2007.  It introduces us to the main character, Isaac Bell.  Bell is a tall, lean detective who works for the VanDorn Detective Agency.  The villain in this story uses one of the first five 1905 Harley Davidson motorcycles ever built to escape after the robbery and triple murder at the Bisbee National bank in Bisbee, Arizona. Julius Edgar Lilienfeld (April 18, 1882 – August 28, 1963) was a Jewish Austro-Hungarian-born German-American physicist and electronic engineer, credited with the first patents on the field-effect transistor (FET) (1925) and electrolytic capacitor (1931).  Because of his failure to publish articles in learned journals and because high-purity semiconductor materials were not available yet, his FET patent never achieved fame, causing confusion for later inventors. Carey Holzman (born June 23, 1968 in Detroit, Michigan) is an IT professional, author, freelance journalist and former co-host of Craig Crossman's nationally syndicated radio show, "Computer America".  Holzman was the first US journalist to bring media attention to the leaking capacitor plague.  Holzman was the author of the first edition of "The Healthy PC" by McGraw-Hill (ISBN  ), As of June 2017 he has a youtube channel with over 160 thousand subscribers and over 200 videos. Pieter van Musschenbroek (14 March 1692 – 19 September 1761) was a Dutch scientist.  He was a professor in Duisburg, Utrecht, and Leiden, where he held positions in mathematics, philosophy, medicine, and astronomy.  He is credited with the invention of the first capacitor in 1746: the Leyden jar.  He performed pioneering work on the buckling of compressed struts.  Musschenbroek was also one of the first scientists (1729) to provide detailed descriptions of testing machines for tension, compression, and flexure testing.  An early example of a problem in dynamic plasticity was described in the 1739 paper (in the form of the penetration of butter by a wooden stick subjected to impact by a wooden sphere). Christian James Lambertsen (May 15, 1917 – February 11, 2011) was an American environmental medicine and diving medicine specialist who was principally responsible for developing the United States Navy frogmen's rebreathers in the early 1940s for underwater warfare.  Lambertsen designed a series of rebreathers in 1940 (patent filing date: 16 Dec 1940) and in 1944 (patent issue date: 2 May 1944) and first called his invention "breathing apparatus".  Later, after the war, he called it "Laru" (portmanteau for Lambertsen Amphibious Respiratory Unit) and finally, in 1952, he changed his invention's name again to SCUBA (Self Contained Underwater Breathing Apparatus).  Although diving regulator technology was invented by Émile Gagnan and Jacques-Yves Cousteau in 1943 and wasn't originally related to rebreathers, the current use of the word SCUBA is largely attributed to Gagnan's and Cousteau's invention.  The US Navy considers Lambertsen to be "the father of the Frogmen". The collection includes more than 3,000 water vessels.  The permanent exhibition introduces us to the world of these water vessels and the history, typology and process of water jug making.  Monographic exhibitions are located on the second floor of the museum.
