Frederick Tisdall was one of three Canadian pediatricians who developed the infant cereal Pablum. He first started working at The Hospital for Sick Children in 1921. In 1929,at the age of 36, he was made Director of the Nutritional Research Laboratories. There, he and his colleagues worked for many months to make the cereal known as their greatest accomplishment. The Osler Library at McGill University holds a small collection of his letters.
After his death, the questions were raised about the ethics of post-war experimentation he was carried out with Lionel Bradley Pett involving First Nations communities, known as the First Nations nutrition experiments.
