Jens Bodewalt Lampe (November 8, 1869 – May 26, 1929) was a Danish-born American composer, arranger, performer and band-leader of ragtime and syncopated dance music. Lampe was born in Ribe, Denmark to Christian and Sophia Lampe. In 1873, his family moved to St. Paul, Minnesota, where his father took over leadership of the Great Western Band. Lampe was a child prodigy on the violin and became the first chair violinist for the Minneapolis Symphony at age 16. He met and married his wife, Josephine, while receiving tuition in Chicago in 1888. In the early 1890s, he and his wife moved to Buffalo, where they had four children, Walter, Petra, Dorothy and Joseph Dell (known later as "Dell"). At this time, he began composing and publishing his own music and led a dance orchestra.
