His father, William Goodison, was a pharmacist and urged his son to study under professor Austin of Trinity College, Dublin.
William Goodison, then a young assistant surgeon under George Treyer,[5] served in Melikia, a village near Lefkimmi in southern Corfu-island, and studied, on the field, the symptoms of the remittent fever and the plague which struck the region.
Goodison published the results of his observations in an article, which appeared in the medical periodical Dublin Hospital Reports in 1817.
[6] After the elimination of the plague epidemic in Corfu, the 75th Regiment of Foot moved, in August 1817, to the island of Lefkas, where it stayed until the end of 1820.
[7] During his service in Corfu and the Ionian Isles, Goodison took advantage of his stay there and compared the topography of these islands against the descriptions of Homer's Odyssey and other texts of ancient and modern writers.
