Leo Francis Corrigan (August 30, 1894 – June 12, 1975) was an American real estate investor and developer, who was described as the country's largest landlord.
In 1917, one of his clients, a real estate investor, offered him a job leasing office space downtown.
He soon struck out on his own, buying and building on a vacant lot at the corner of Lemmon Avenue and Wycliff Street.
Carrigan married Catherine Redman in 1917 and they had two children, Louise and Leo Francis Jr.
He and his wife donated to Southern Methodist University and Austin College to endow chairs in real estate.
