About Karl Barry Sharpless
Karl Barry Sharpless (born April 28, 1941) is an American stereochemist. He is a two-time Nobel laureate in chemistry, known for his work on stereoselective reactions and click chemistry. Sharpless was awarded half of the 2001 Nobel Prize in Chemistry "for his work on chirally catalysed oxidation reactions", and one third of the 2022 prize, jointly with Carolyn R. Bertozzi and Morten P. Meldal, "for the development of click chemistry and bioorthogonal chemistry". Sharpless is the fifth person (in addition to two organizations) to have twice been awarded a Nobel prize, along with Marie Curie, John Bardeen, Linus Pauling and Frederick Sanger, and the third to have been awarded two prizes in the same discipline (after Bardeen and Sanger). == Early life and education == Sharpless was born April 28, 1941, in Philadelphia, Pennsylvania. His childhood was filled with summers at his family cottage on the Manasquan River in New Jersey. This is where Sharpless developed a love for fishing that he would continue throughout his life, spending summers in college working on fishing boats. He graduated from Friends' Central School in 1959, and continued his studies at Dartmouth College, earning an A.B. degree in 1963. Sharpless originally planned to attend medical school after his undergraduate degree, but his research professor convinced him to continue his education in chemistry. He earned his Ph.D. in organic chemistry from Stanford University in 1968 under Eugene van Tamelen.
