She was born in Bergen as a daughter of priest Johan Cordt Harmens Storjohann (1832–1914) and Nanna Storjohann, née Holmboe (1838–1898).

Michelet started her career in the public sphere as a children's writer. Her books were originally meant for her own children, but reached a wider audience. Titles include Puk (1901), Hos mormor (1902), I Svalehuset (1902) and Usynlige magter (1906). She was also a teacher at Sandvika Middle School from 1905 to 1910.

In the 1910s she mostly wrote books that supported Christianity, motherhood and family, such as Det kristne hjem (1913) and Den selverhvervende kvindelige ungdom (1915). She also began contributing extensively to periodicals and weekly magazines for women. Her organizational platform was Hjemmenes Vel ("Welfare of Homes"), which sought to improve domestic conditions for women and families. The first Hjemmenes Vel had been established in 1898, and in 1915 Michelet was a main initiator behind the foundation of Hjemmenes Vels Landsforbund, a national association. She chaired this organization from 1915 to 1934, overseeing the name change in 1933 to the Norwegian Housewives' Association (from 1997: the Norwegian Women and Family Association). Michelet also chaired the Nordic Housewives' Association from 1933 to 1937, whereupon she became honorary president, and was a leading figure in the International Council of Women.
