Johann Hugo von Wilderer (b. 1670–d. 1724). 

Johann Hugo von Wilderer was born in Bavaria.  It is believed he studied with the Venetian Giovanni Legrenzi.  At age 30 he was appointed Kapellmeister of the Duesseldorf  court, where he worked until the death of the prince-elector in 1716.  The new prince united several groups of musicians in western Germany (Duesseldorf, Mannheim, and Heidelberg).  With the help of Wilderer and others, the prince built the foundations for the famous Mannheim Orchestra  Wilderer probably met Haendel during the latter’s visits to Duesseldorf in 1710, 1711, and 1719.  Wilderer wrote relatively few sacred works, but his Missa brevis in G minor was copied out by J. S. Bach, who seems to have borrowed a few elements from it for the Kyrie of his B minor Mass.
