The volumes in the ""Portraits of Pioneers in Psychology"" series promote outstanding but sometimes neglected contributions of groundbreaking early psychologists. Through the examination of these individuals' lives and work, the readers will come to understand specific schools, fields, and perspectives in psychology and will gain an appreciation of how psychology has evolved in both methodology and focus. The latest volume of the series ""Portraits of Pioneers in Psychology"", Vol. VI pays tribute to some of the big names in psychology, such as Abraham Maslow, Henry Murray, Edmund Clark Sanford, and James McKeen Cattell, as well as some lesser-known luminaries, who, nonetheless made significant contributions to the field. Through this collection of 17 biographies emerges a sense of excitement, and of the often difficult work that shaped research and practice across a range of fields, including clinical psychology, child psychology, individual differences, comparative psychology, industrial/organizational psychology, and sport psychology. The volume closes with a thoughtful discussion of the contributions made and challenges faced by Kenneth Clark, the first African American to serve as president of the American Psychological Association. Clark's scholarly work on racial prejudice and efforts at uniting social science and social activism helped lay the groundwork for the landmark Supreme Court ruling in Brown v. Board of Education, which ended segregation in the schools.
