Tinne Vammen (November 23, 1942 – October 5, 2016) was a Danish historian, considered a pioneer in women's history research in her country.

Tinne Vammen was born in Hillerød, Denmark, in 1942. ^{[1] [2] [3]} Growing up in nearby Lillerød, she was one of five children born to Knud Ejnar Daniel Knudsen, an agribusinessman and local Venstre party politician, and Emilie Christiane Mouritzen, a former nursing student. ^{[1] [2]}

In 1961, she graduated from the Frederiksborg State School, then worked as an au pair in England. ^{[1] [2]} She continued her studies at the University of Copenhagen, first in English and then in history. ^{[1] [2]} As a student, she became involved in youth activism, including the Slumstormer [ da] squatting movement and the Red Stocking women's rights movement. ^[1] An essay she wrote about her experience in the Red Stocking movement was later published in the anthology Sisterhood Is Global. ^[4]

Vammen is considered a pioneer in Danish women's history research. ^[1] She became one of the first academics in the University of Copenhagen's History Department to examine women's history, conducting in-depth archival studies and producing sweeping narratives of women's role in Denmark's past, as well as helping establish the first interdisciplinary courses in women's research in 1972. ^[1] She began lecturing in the History Department after obtaining her master's of philosophy in 1973. ^{[1] [2]} Later, in the 1980s, she also taught at the Folkeuniversitetet [ da]'s Center for Women's Research. ^[1]

From 1982 to 1984, she served on the editorial board of the journal Kvinders, which promoted women's research. ^{[1] [5]} Due to her gender and the subject matter she worked on, she faced difficulties throughout her career, and much of her research was self-financed. ^{[1] [2]} Nevertheless, she also worked to increase the participation of female students in history programs. ^[2] She also worked on an effort to introduce women's history into high school curricula in the early 1980s, and collaborated on women's history initiatives across the Nordic countries. ^[2]

Her first book, Rent og urent (1986), comprised a groundbreaking discussion of women in the Capital Region, focusing on housemaids and their mistresses, from 1880 to 1920. ^{[1] [2] [3]} Her study of the Copenhagen Women's Home [ da] was published in 2002 as Midlertidigt ophold. Kvindehjemmet i 100 år. ^[2] She co-edited the anthologies På tröskeln till välfärden (1995), Charitable Women (1998), and Den privat-offentliga gränsen (1999). ^[1] She also contributed 86 biographies to the Dansk kvindebiografisk leksikon, a collection of Danish women's biographies. ^{[1] [2]}

In 1966, she married fellow academic Hans Nicolaj Møller Vammen. ^{[1] [2]} They had two children, Morten (born 1967) and Ida (born 1979), before dissolving their marriage in 1981. ^{[1] [2]}

She died in 2016, of cancer, at age 73. ^[2]
