While Prince Philip wasn't always close with his mother, she did write an emotional letter to him prior to her death.
Philip's mother, Princess Alice of Battenberg, was born at Windsor Castle in 1885 to parents Prince Louis of Battenberg and Princess Victoria of Hesse and by Rhine. Alice, who was one of Queen Victoria's great-grandchildren, was born with congenital deafness and learned to lip read, Tatler reported.
