Andersen earned his Ph.D. in political science from the University of Chicago. As a part of his field work, he lived in India for four years from late 1960s through early 1970s. There he came in contact with Akhil Bharatiya Vidyarthi Parishad. That association led to an introduction to M. S. Golwalker – the head of RSS. His scholarship has focussed on the RSS and Indian politics. He considers Lloyd and Susanne Rudolph as his mentors, states an article in The Indian Express.
Scholarship of the Rashtriya Swayamsevak Sangh
Andersen, with Sridhar D. Damle, co-authored the 1987 book The Brotherhood in Saffron: The Rashtriya Swayamsevak Sangh and Hindu Revivalism. The book has been called an authoritative, detailed examination of the Rashtriya Swayamsevak Sangh, including its early growth in the pre-independence period, its organization, the function of its various officers and the evolution of its ideology. "The founders of the RSS concluded that the Hindu social body was weak and disorganized because dharma was neither clearly understood nor correctly observed." It was the task of the Sangh's members to create a stable Hindu society and culture. and Nistula Hebbar. The authors avoid categorizing the RSS as having an ideologically loaded framework and treat it with "understanding and objectivity." Roughly half the book focuses on the political involvement of the Sangh, with the Bharatiya Jana Sangh, the Janata Party and the Bharatiya Janata Party, and includes information about how the Sangh exerts influence on the political partners. In 2018, Andersen and Damle co-authored The RSS: A View to the Inside. After the book's publication, the Political Science scholar Ashutosh Varshney remarked that "Andersen is the only scholar who has observed or studied the RSS for nearly five decades". According to Andrew Nathan, Andersen and Damle "take an exceptionally well-informed look at the RSS, including its relations with affiliate organizations", and discuss how the "core concept of Hindutva, or “Hinduness,” is now glossed as loyalty to a vaguely defined Indian civilization rather than adherence to specific religious practices, a revision made easier by the unsystematic character of Hindu beliefs" while still "espousing aggressive anti-Muslim and socially conservative positions". Andersen calls the book as a sequel to The Brotherhood in Saffron book published in 1987, and one that presents the significant changes in India and the RSS since 1987. According to Andersen, the RSS has formed and grown over a hundred affiliated organizations to help penetrate nearly every part of India. These affiliates now play an active role in lobbying the policy processes. Walter Andersen has also written a four-part series of articles on the Rastriya Swayamsevak Sangh in the Economic and Political Weekly in 1972.
