Abstract
John Lisman had a passionate connection with life, art and science. He lived his life till the end with enthusiasm and energy, passing away on October 20, 2017. John said many times that he did not understand how people could retire from science—he personally would not know how to live without intellectually challenging himself every day. When he found out that he had cancer, and that his expected life span was “short or very short” he announced that he and his family were “not into grieving.” So it was business as usual. He just added the challenge of understanding cancer and treatment options to his list of challenges. He worked harder than ever, while making more time for his family and friends in the last months.
