The family palace housed seven grand pianos and each of the siblings pursued music "with an enthusiasm that, at times, bordered on the pathological". The eldest brother, Hans, was hailed as a musical prodigy. At the age of four, writes Alexander Waugh, Hans could identify the Doppler effect in a passing siren as a quarter-tone drop in pitch, and at five started crying "Wrong! Wrong!" when two brass bands in a carnival played the same tune in different keys. But he died in mysterious circumstances in May 1902, when he ran away to America and disappeared from a boat in Chesapeake Bay, most likely having committed suicide.
