Who is Muzio Clementi from The Great Pianists and what is their importance?

Muzio Clementi is the name of an Italian-born English piano virtuoso who was considered no match to Mozart in a competition sponsored by the Emperor. Ironically, there was no winner. Clementi's technical skill was overcome by Mozart's art, taste and feeling. Mozart disliked Clementi's stronger technical skills and was offended by his unconventional romantic modulations. Muzio Clementi was born in 1752 Italy and raised by an English Member of Parliament. Peter Beckford saw musical genius in the fourteen year old and brought him to Wiltshire, England.
