Henriette Blanke-Belcher (February 16, 1882 – March 1958), also known as Henrietta Blanke-Belcher and later as Henriette B. Melson, was an American composer of popular music, especially waltzes and ragtime tunes.

Henriette was raised in Chicago, and Detroit;[1] her father died in the latter city when she was a teenager.

[6] "I want to become known as a waltz writer exclusively," she said in 1902, but she also wrote ballads and novelty songs.

[13][14] Henriette Blanke married Frederick E. Belcher, an executive at Jerome H. Remick,[15] in 1905, in Detroit.

The couple lived in New York, and had one child, Maxine F. Belcher, born in 1906.
