Trumpeter Adolph Herseth has died at the age of 91. He passed away on 13 April (13) at his home in Oak Park, Illinois.
Born in Minnesota, he graduated from Luther College in Iowa with a degree in mathematics and served in the U.S. Navy during World War Two as a musician.
Herseth went on to become a principal performer at the Chicago Symphony Orchestra, where he played for 53 years until he gave up his post in 2001.
He retired in 2004 and has since been recognised as the "most respected and influential orchestral trumpeter of the last half-century," according to the Chicago Tribune.
