David P. Tyndall

David P. Tyndall (May 17, 1890 — January 6, 1970) was a leading Irish businessman in the 20th century, and played the major role in helping modernize the wholesale and retail grocery trade, consolidate it, and enable the family grocery shop owner adapt to the advent of supermarkets.

The grandson of John Tyndall from Newcastle, County Dublin, a saddlery and forge owner, he was also descended from an O'Donnell of Tyrconnell, through a great-grandmother from Glenties, County Donegal. A native of Chapelizod, he left school at the age of 14 to work and in due time become a leading entrepreneur. He married Sarah Gaynor (January 1, 1892 – August 19, 1978) from Inchicore in Dublin, in 1914, and had six children, William, David, Jr. ("Dave"), Annie, Mona, John, and Stephanie. They settled in Glasnevin.

William and Dave joined their father's business when they reached the age of 16. Annie died in 1934, a young woman. Mona joined the Holy Rosary Sisters and became a medical doctor and missionary in Africa. John became a leading Dublin psychiatrist. Stephanie married an Army officer, Patrick Denis O'Donnell.

In 1931, David P. Tyndall decided to start his own business, having been a wholesale butter merchant for some years. With a partner, they founded Doherty, Tyndall & Co. Ltd., distributing groceries by horse and two-wheeled cart. By 1941, the firm had expanded to thirteen employees, including his two older sons, Willie and Davy. Transport switched from horse to motor. In 1943, the company became wholly owned as D. Tyndall & Sons, Ltd. Another company was founded and added in 1957, Farm Sales Ltd.

In the years that followed, other companies were taken over, and the business diversified and expanded, in tandem with technological innovations, commercial initiatives, and marketing prowess. Modern business methods were developed, such as “cash and carry” wholesaling in 1964, and incentive schemes for workers were introduced. Upon his retirement he had achieved the premier position in Ireland for his influence on the wholesale and retail grocery sector, with the largest network in the country.
