Mark Rowe lectured to third year Pharmacy students at Sydney Uni...I then remembered him from Springwood, where he went to school, around the late 1950s, going to the catholic school while I went to the public school. He then went to school in Strathfield, while I went to school in Croydon a year or so later. I am sure this must be he same Mark Rowe I remember..his pharmacology lecture was on 'seretonin'.. a substance thought to exist in the brain. I wa sad to see he was accidently killed...what a great life wasted.
