From the above it may be suspected that Clementi was not only player and composer, but man of business. He had been very successful in money-making in England from the start, and it was not many years before he accumulated a sufficient amount to buy an interest in the firm of Longman & Broderip, “manufacturers of musical instruments, and music sellers to their majesties.” The failure of the house, by which he sustained heavy losses, induced him to try his hand alone at music publishing and piano-forte manufacturing; and his great success (the firm is still extant in the person of his partner’s son, Mr. Col-lard) proves he was an exception to the majority of artists, who rarely possess business talents. Clementi met many reverses in his commercial career. In March, 1807, the warehouses occupied by Clementi’s new firm were destroyed by fire, entailing a loss of about forty thousand pounds. But the man’s courage was indomitable, and he retrieved his misfortunes with characteristic pluck and cheerfulness. After 1810 he gave up playing in public, and devoted himself to composing and the conduct of his piano-forte business, which became very large and valuable. Himself an inventor and mechanician, he made many important improvements in the construction of the piano, some of which have never been superseded.
