Because of many written sarcastic remarks by his good friend Wolfgang Amadeus Mozart, it has been assumed that Ignaz Leutgeb was "slow of wit." Whether or not this is true is not certain, however Leutgeb was without doubt a fine horn player. Many critics of the time wrote about his superior musical and technical abilities.
In 1773, after playing first horn in the band of the Prince Archbishop of Salzburg and touring various European cities, he settled in Vienna. With a loan from Leopold Mozart he opened a small cheese shop and in time, he became a very successful merchant.
