Maurice George O'Shea (13 June 1897 – 5 May 1956) was one of Australia's most respected winemakers, and is often referred to as the father of Australia's modern winemaking. Maurice was the son of Irish born wine and spirit merchant John Augustus O'Shea (died 1912) and Leontine Frances, née Beaucher.[1][2]
In 1932, O'Shea sold half of this business to McWilliam's Wines Pty Ltd. O'Shea stayed on as Manager and Director of the new subsidiary Mount Pleasant Wines Pty Ltd. In 1941 he sold the remaining half of the business and stayed on as manager and winemaker.
Maurice O'Shea named many of his wines after his friends, rather than the more orthodox method of naming them with a Bin Number of letter. The names included "Elizabeth", "Henry" and "George".[7] McWilliams Mt. Pleasant 'Elizabeth' Semillon is still made.[8]
O'Shea most often made very small quantities of wine, often only one 2,275 litre cask.[6]
