Joseph "Spud" Murphy was an Irish businessman and inventor, best known for being the founder of Tayto and inventing the cheese and onion-flavoured crisp.
Murphy was born on 15 May 1923 to Thomas Murphy, a small business owner on Thomas Street and Mary James "Molly" Sweeney, who owned a wallpaper and paint shop on the same street.
With his friend, Seamus Burke, he invented the cheese and onion crisp while mixing flavours at his kitchen table.
Gaining success with the crisp, Murphy moved his company twice, first to Mount Pleasant Avenue and then to Harolds Cross.
[2] After the great success of his company, Murphy sold Tayto in 1983 and lived his later years in Spain, where he passed away on September 28, 2001 at the age of 78.
