The 6th son and 8th child of London tailor, Edward Ezekiel Nathan and his wife born Rachel Davis, he emigrated to Australia in 1853 at the time of the Victorian gold rush and opened a store in central Melbourne supplying goldminers.
He married Dinah Marks in Melbourne just before moving to New Zealand at the end of 1857 to join his sister's husband's importing business, Jacob Joseph & Co.
Joseph Nathan & Co became best known for its New Zealand made dried cow's milk product, Glaxo, a baby food developed in the early twentieth century.
New factories, laboratories and offices were completed that year at Greenford, Middlesex[6] and pharmaceuticals including penicillin were added to Glaxo's range.
