Peter Louis Waller AO FASSA FAAL (10 February 1935 – 8 October 2019) was an Australian jurist.
Realising their Jewish family was in danger of persecution from the increasingly threatening National Socialist regime in Germany, Waller's parents managed to flee to Australia in 1938.
When he graduated in 1956, he went to England where he obtained a Bachelor of Civil Law from the University of Oxford (Magdalen College) with First Class Honours.
Waller's career in academia began in the late 1950s, when he was appointed tutor and then senior lecturer at Melbourne University.
Its Foundation Dean, Professor David Derham, was a friend of Waller's who knew of his teaching and intellectual abilities.
Through his teaching and research, he is credited with elevating the status of criminal law in Australia, a field which had often been looked down upon.
He wrote prolifically on in-vitro fertilisation, a practice which was coincidentally pioneered in the Medicine Faculty at Monash.
At the Law Reform Commission, Waller chaired a groundbreaking committee which looked at the possible legal framework surrounding IVF for the first time.
