Interior Design Masters contains 300 biographical entries of people who have significantly impacted design. They are the people, historical and contemporary, that students and practitioners should know. Coverage starts in the late-Renaissance, with a focus on the twentieth and twenty-first centuries. The book has five sections, with the entries alphabetical in each, so it can serve as a history text book and a reference guide. The seventeeth- and eighteenth-century section covers figures from Thomas Chippendale to Horace Walpole. The nineteenth-century section includes William Morris and Candace Wheeler. The early twentieth-century section presents modernism's design heroes, including Marcel Breuer, Eileen Gray, and Gilbert Rohde. The post-World War II designers range from Madeleine Castaing to Raymond Loewy.

The final contemporary section includes Ron Arad and the Bouroullec brothers. These are the canonical figures who belong to any design history. The book also contains less well-known figures who deserve attention, such as Betty Joel, the British art deco furniture designer; Paul Veysseyre, the Frenchman active in China in the 1930s; and more recently Lanzavecchia-Wai, the Italian-Singaporean duo whose work ranges from health care to helicopters. Global in its coverage, the book is richly illustrated with over 600 black and white and color photographs.
