A pdf version of a slide presentation about the life and contributions to career psychology, counseling and higher education of John L. Holland. Includes biographical material describing his life, education, and work from college days throughout his life. Includes information about the nature of his research and professional contributions, his work settings, the influence of others on his life and work, and his influence on others. The slides may be useful in graduate seminars or courses on career development, career assessment, history of psychology or counseling, or theory development. One file contains only the slides for use when making a presentation and a second file contains slides with notes pages that provide instructors with hints for making a presentation as well as guidance on reading material for instructors and students. This presentation evolved from an invited address to the Maryland Career Development Association a few years after Holland’s death. The topic of the presentation was expanded into a book containing an autobiography of Holland as well as other material. The present slides refer to the book as well as other ancillary sources for graduate courses or seminars.
