Who did Herbert Boyer have a conversation with in Hawaii?

Boyer observed that these enzymes have the capability of cutting DNA strands in a particular fashion, which left what has became known as ‘sticky ends’ on the strands. These clipped ends made pasting together pieces of DNA a precise exercise. This discovery, in turn, led to a rich and rewarding conversation in Hawaii with a Stanford scientist named Stanley Cohen. Cohen had been studying small ringlets of DNA called plasmids and which float about freely in the cytoplasm of certain bacterial cells and replicate independently from the coding strand of DNA. Cohen had developed a method of removing these plasmids from the cell and then reinserting them in other cells. Combining this process with that of DNA splicing enabled Boyer and Cohen to recombine segments of DNA in desired configurations and insert the DNA in bacterial cells, which could then act as manufacturing plants for specific proteins. This breakthrough was the basis upon which the discipline of biotechnology was founded..
