Claim: The Boehm and Oehler systems have been substituted with the Albert system for clarinetists.
Evidence: The Boehm clarinet was initially most successful in France—it was nearly the only type of clarinet used in France by the end of the 1870s—but it started replacing the Albert system clarinet and its descendants in Belgium, Italy, and America in the 1870s and—following the example of Manuel Gómez, a prominent clarinetist in London who used the Boehm system and the Full Boehm system clarinet—in England in the 1890s. 
It has been largely replaced by the Boehm system and Oehler system.
