Tan was born on 11 June 1930 in
Batavia, Dutch East Indies (now Jakarta, Indonesia), Education was important to the family, and her parents hired a governess to ensure the children completed their homework. Tan attended a
Hollandsch Chineesche School, where she received high marks, and continued to a
Hogere Burgerschool. Tan studied for her bachelor's degree at the Department of
Sinology at the University of Indonesia. In her third year, she entered a scientific writing competition that was organized by the Catholic Scientific Circle, winning the competition with her sociological field study. Tan later wrote that that was one of the factors that interested her in studying sociology formally; the contemporary focus on
Chinese literature bored her. Tan later graduated from the University of Indonesia in 1959. In January 1959, Tan arrived in
Ithaca, New York, to begin her studies at Cornell University. Despite slight
culture shock, Tan enjoyed her studies, under the guidance of Skinner and the sociologist
Robin Murphy Williams. Tan later described her time at Cornell as "some of the most intellectually and stimulating years" of her life. She received her
Master of Arts in
sociology in 1961, She later described this period as a time of great anxiety, as the political turmoil that Indonesia was experiencing – including a deteriorating economy and growing
communist party – led many students to fear that their fellowships would be cancelled. Tan took her oral examination with
Wolfram Eberhard,
Herbert Blumer,
Robert Blauner,
Neil Smelser, and
Daniel Lev as her examiners. After passing, Tan began work on her dissertation. Tan wrote her dissertation under the guidance of Eberhard, Blauner, and Lev, with approval given on 13 June 1968. Tan became the first Indonesian to receive a PhD in sociology from Berkeley as well as the first female Indonesian with a doctorate in sociology. Tan noted that the students and professors seemed disinterested in Indonesian studies, and thus she had taken high-school students in San Francisco as her research subjects. ==Academic activities and activism==
