A brilliant linguist and able to read at least 11 languages, he taught himself English and soon after made that opportune visit to Professor Robinson's office.
In 1961 at a conference of Australian sheep breeders in Melbourne, Professor Robinson and Dr Salamon asked around for sheep producers willing to let the scientists conduct experiments on their flocks. Mr Walker, eager to find better methods and techniques of collecting semen from stud rams and artificially inseminating his ewes, was delighted to assist.So began a highly productive scientific collaboration that lasted for almost half a century.
His linguistic skills allowed him to translate foreign scientific papers previously not accessible to Australian scientists, and in some cases, to debunk false scientific claims by the Soviets.
