Fault having no way to forgive to such an extent even cause has committed descendants in old age , his music to Strauss clan.In 1901, Edward · Strauss leads a regiment to visit US after performing coming-back , a band is dissolved abruptly because of being at outs with band,the instrument exists with possessions to have entered a pawnshop, feasible John · Strauss father and son gets through hardship building-up's , the eminent Strauss philharmonic orchestra is lost in a cloud at this point in that time entire Europe reputation. Edward and one kiln boss have signed a agreement in 1907,with husband or lover's 2 grams of price per kilogram, need to sell a batch of "wastepaper" doing fuel for kiln. On October 22, a truck has moved this batch of "wastepapers" almost all kinds of kilogram to a kiln , go ahead has filled in a furnace chamber.

以至于在晚年，他对施特劳斯家族的音乐事业犯下了后人无法饶恕的罪过。1901年，爱德华·施特劳斯率团访美演出归来后，因与乐队不和，突然将乐队解散，把所有乐器存进了当铺，使得约翰·施特劳斯父子历经艰辛建立的，在当时整个欧洲声名显赫的施特劳斯乐团就此烟消云散。1907年，爱德华与一家瓷窑老板签了一个协议，以每公斤2克郎的价格，要卖一批"废纸"给瓷窑作燃料。10月22日，一辆卡车将这批几百公斤的"废纸"拉到了瓷窑，开始填入炉膛。
