Childhood
Felix Zandman was born to a
Felix Zandman shared this hideaway with three other Jewish refugees. One of them, his uncle Sender Freydowicz, taught him trigonometry and advanced mathematics in the long hours of darkness.[4] The advancing Soviet Army liberated them in July 1944. He stayed with other survivors in Poland until he was able to emigrate legally to France in the summer of 1946.
Professional life as an employee
Zandman worked initially for two years as a lecturer at the
In 1956, Zandman presented his methods and self-developed instruments for the first time in the U.S.. He was able to establish important contacts with leading professors and well-known users of its specific field. He was eventually employed by the company
Professional life as an entrepreneur
In 1960 Felix Zandman and Sidney J. Stein[5] presented a development of resistor film (an electrical component of very high temperature stability) and put the potential of this invention to develop, based on inventions made by previous researchers established in the industry. This component was called a metal foil resistor. In spite of the problems encountered, and working with many collaborators, it was possible to develop this resistor which had high precision and, above all, stability in the presence of extreme temperature changes such as those found in the aeronautical and space industry. In essence the metal foil resistor is a component formed by a ceramic base to which is attached a metal with a small thickness. Zandman's idea was as follows: Assuming that the component is at room temperature and the temperature then increases, the electrical resistance of the metal due to the increase in temperature also increases. As the temperature increases the metal tends to increase its length when it expands. However, being stuck to a ceramic structure with a much greater thickness, the metal can not expand lengthwise and its thickness increases instead, with a reduction in electrical resistance. The effect is that the increased resistance is compensated and hardly changes.
To this end he founded the company

Book and documentary
His autobiography "Never the last journey" co-written with David Chanoff was published in 1995.[11][12]
Zandman's life was the subject of the 2015 documentary "The Last Victory - the Story of Felix Zandman" which was directed by Haim Hecht and produced by Roy Mandel.[13]
