Question: Jean Fréchet was a good friend of which American chemist and peace activist?

<P0-S0> Fredrik Stang Heffermehl (born 11 November 1938) is a Norwegian jurist, writer and peace activist. <P0-S1>  He formerly worked as a lawyer and civil servant from 1965 to 1982 and was the first secretary-general of the Norwegian Humanist Association from 1980 to 1982. <P0-S2>  He later made his mark as a writer and activist for peace and against nuclear arms. <P0-S3>  He is the honorary president, and former president, of the Norwegian Peace Council, a former vice president of the International Peace Bureau, which received the 1910 Nobel Peace Prize, and a former vice president of the International Association of Lawyers against Nuclear Arms. <SEP> <P1-S0> Professor Jean M.J. Fréchet (born August 19, 1944, Burgundy, France), American chemist, is a Professor Emeritus at the University of California, Berkeley. <P1-S1>  In addition, he is the head of Materials Synthesis, Materials Science Division,of the Lawrence Berkeley National Laboratory, Director of the Organic and Macromolecular Facility for the Molecular Foundry, Lawrence Berkeley National Laboratory, and Vice-President for research at King Abdullah University of Science and Technology. <P1-S2>  He has authored nearly 900 scientific papers and holds over 70 United States Patents. <P1-S3>  His research areas include organic synthesis and polymer chemistry applied to nanoscience and nanotechnology with emphasis on the design, fundamental understanding, synthesis, and applications of functional macromolecules. <P1-S4>  He was a good friend of influential American chemist Linus Pauling and consistently mentions him in his organic chemistry lectures. <P1-S5>  As of March 2011, he is 16th on the Hirsch index rating of all living chemists with an H-index of 105. <P1-S6>  He is an elected fellow of the American Association for the Advancement of Science, the American Chemical Society, and the American Academy of Arts and Sciences, and an elected member of the US National Academy of Sciences, the US National Academy of Engineering, and the Academy of Europe (Academia Europaea). <SEP> <P2-S0> Mary MacGregor is Mary MacGregor's fourth and final album, released in 1980. <P2-S1>  After recording two albums for Ariola Records - who had also released a Mary MacGregor compilation - MacGregor had recorded the track "Good Friend" for the 1979 film "Meatballs" whose soundtrack album was released by RSO Records. <P2-S2>  "Good Friend" had been sufficiently successful - reaching #39 on the "Billboard" Hot 100 - for RSO to sign MacGregor in December 1979. <P2-S3>  This resultant self-titled album produced a minor hit in "Dancin' Like Lovers" - #72 in the spring of 1980 - followed by the non-charting "Somebody Please" which was evidently MacGregor's final single release. <P2-S4>  The "Mary MacGregor" album is out of print and has never been issued on CD. <SEP> <P3-S0>  He published more than 1,200 papers and books, of which about 850 dealt with scientific topics. " <P3-S1> Linus Carl Pauling (February 28, 1901 – August 19, 1994) was an American chemist, biochemist, peace activist, author, and educator. <P3-S2> New Scientist" called him one of the 20 greatest scientists of all time, and as of 2000, he was rated the 16th most important scientist in history.
