Laura Constance Netzel (née Pistolekors; 1 March 1839 — 10 February 1927) was a Finnish-born Swedish composer, pianist, conductor and concert organizer who sometimes used the pseudonym N. Lago.[1] She was born in Rantasalmi, Finland, and was proud of her Finnish heritage throughout her life, even though she was just one year old when she moved permanently to Stockholm.[2] Netzel studied piano with Mauritz Gisiko and Anton Door, voice with Julius Günther and composition with Wilhelm Heinze in Stockholm and Charles-Marie Widor in France.
