Alexander Carlisle(1854-1926) brother-in-law to Lord William J. Pirrie was one of the men involved with designing the Olympic class ocean liners. His main role of responsibility was the ships safety systems such as the watertight compartments, life boats, etc.[1]
After an argument with his brother-in-law on the manner of the numbers of lifeboats being cut short he left Harland and Wolf, and ended his involvement in the designing of the Olympic class liners. The Olympic class liners would be the last ships that he would ever be involved with.[2]
