Obituary: Prof. Harold V. McIntosh, March 11, 1929 - November 30, 2015

Professor Harold V. McIntosh was a prominent researcher who dedicated his life to Science. He was a big promoter of educating young students in several scientific fields simultaneously, such as physics, history, mathematics, biology, chemistry, and computer science. McIntosh was born in Colorado, USA in 1929 and died last November in Puebla, Mexico. McIntosh's legacy in different scientific fields is an example of dedication, passion and principles, in order to investigate problems from the easiest perspective, with didactic and visual interpretations, to establish later a formal solution. He was a great mentor and inspiration for many generations of students and researchers, and will be always remembered and honoured as a brilliant scientist and an exceptional person.
