This article is a review of the academic works of American sociologist James Bossard. During his life he wrote a vast number of articles and books on family, marriage, childhood and parenting, using a variety of methods for collecting and analyzing information. Despite his active academic and social life, James Bossard is very little known in the Russian-speaking environment. James Bossard creates his own set of approaches towards studying family, which should cover all significant aspects of the latter. Said set is based on approaches that can be divided into three main categories, which will be discussed in the review: family rituals, family heterogeneity and family as a field for change. Meanwhile he also described other issues: happiness and unhappiness in the family, the differences between large and small families, the role of children in the family, rites of passage, the impact of war on families. James Bossard is also worthy of interest as a productive researcher with unconventional approaches to working with material, as well as a peculiar sign of the time. The main goal of the author of this review is to draw attention to this sociologist’s legacy, since many of his works are also relevant in modern Russia.
