Born in Keflavík, 29 march, 1944. Icelandic keyboard player, arranger, songwriter and producer.
Worked in Scandinavia and central Europe from the late 60's into the mid 80's with artists such as Giorgio Moroder and Donna Summer. Note that because many typesetting systems have problems with the Þ character in his first name, it has appeared on records as Thor, Thorir, Porir, and so on and his initials as T, P, R, Th. and so on.
