"The American steel magnate Henry Clay Frick engaged a suite in February 1912 but canceled when Mrs. Frick sprained her ankle during a Mediterranean cruise. J. P. Morgan took over the booking but canceled when business interests lengthened his stay abroad. The booking was then assumed by Mr. and Mrs. J. Horace Harding, but the couple was able to get an earlier sailing date aboard Mauretania. (The suite – B-52, 54 and 56 – finally received a tenant for the voyage when it was occupied by Mr. J. Bruce Ismay.)"
