The seidl & sohn piano, founded by john seidl in germany in may 1910, has so far had a history of 109 years, and the zedel piano, one of the pioneer representatives of traditional pianos, has been held up to the very beginning of "making precious pianos". And from 1925 to 1970, building on john's creation of the seidl & sohn brand, the second generation of the seidel family, gilbert seidl, and the third generation, stephen seidl, made a qualitative transformation and improvement of the cedar piano, and promoted the cedar piano throughout europe and established its brand as "breed for the arts". By the end of the twentieth century, adrian seidl, the fourth generation of the sadr family, brought the brand into the district and established a representative office in hong kong to pass on this hundred-year-old classic。
