ロスチャイルド男爵
Walter inherited the British peerage title "Baron Rothschild" from his father Nathan Mayer Rothschild, 1st Baron Rothschild in 1915. He died in 1937 at Tring Park, Hertfordshire, aged 69, and was buried in Willesden Jewish Cemetery, London. He had no legitimate children and his younger brother Charles Rothschild had predeceased him, so the title was inherited by his nephew (Nathaniel Mayer) Victor Rothschild.
