Mention the role of following scientist H. Boyer.

Herbert Wayne "Herb" Boyer (born July 10, 1936) is a researcher and entrepreneur in biotechnology. Along with Stanley N. Cohen and Paul Berg he discovered a method to coax bacteria into producing foreign proteins, thereby jump-starting the field of genetic engineering. By 1969, he performed studies on a couple of restriction enzymes of the E.coli bacterium with, especially useful properties. He is a recipient of the 1990 National Medal of Science, co-recipient of the 1996 Lemelson–MIT Prize, and a co-founder of Genentech. He was a professor at the University of California, San Francisco (UCSF) and later served as Vice President of Genentech from 1976 until his retirement in 1991.  In 1977, Boyer's laboratory and collaborators Keiichi Itakura and Arthur Riggs at City of Hope National Medical Center described the first-ever synthesis and expression of a peptide-coding gene. In August 1978, he produced synthetic insulin using his new transgenic genetically modified bacteria, followed in 1979 by a growth hormone.
