Composer. She was a Danish composer of the 19th century. In a time when female composers were not easily recognized for their talents, she used the professional male name of Frederik H. Palmer to hide her gender. Her first published piece was "Viennese Waltz" in February of 1841 for the Student Association dance. She wrote the music for eleven pieces, which were published from 1849 to 1853 as a collection, "Romances and Songs." With her pieces featuring both her birth name as well as her pseudonym, another romantic collection was published posthumously in 1892 of 22 songs. The lyrics of these songs were written by various poets of the era. Born into a wealthy household, she was afforded the life of a lady, learning piano and music early from tutors. Her father was considered the wealthiest man in Copenhagen, and she lived all of her life in her family's home, the Zinn House, in Copenhagen. Besides music, she loved art, theater, and literature. In 1829 she married Johan Peter Emilius Hartmann, a prolific composer during the Golden Age in Denmark. The couple had ten children, of which four died as infants. With his pieces at times confused with his father's work, her oldest son was Emil Hartmann, who became a prolific composer before his failing physical and mental health. Her son August Hartmann became a violinist and composer before becoming deaf; August's son became a composer. Her son Carl Christian Hartmann became a successful sculptor as well as composed a few pieces. Her daughter Emma married composer Niels Wilhelm Gade, and her daughter Clara married composer August Winding. Fredrick Hartmann was her youngest son. Her widower, who lived almost another 50 years after her death, remarried in 1855, but there were no children to this union. Children's book author Hans Christian Andersen mentioned her very positively in his memoirs, "Mit Livs Eventyr." Her husband was a colleague of Anderson, composing music to many of his authored pieces. A collection of her piano pieces was published privately by her youngest son Frederik in 1908. The collection was re-published in 2003. She wrote her father's memoirs, "Grandma's Confessions," which gives much insight into the way of life in Copenhagen during the 18th century. With her father-in-law, husband, sons, and grandchildren, the Hartmann family produced four generations of Danish composers.
