James Tennant Baldwin (born 1934) (whose books and articles have been published under the names J. Baldwin, Jay Baldwin, and James T. Baldwin) is an American industrial designer and writer. Baldwin was a student of Buckminster Fuller; Baldwin's work has been inspired by Fuller's principles and (in the case of some of Baldwin's published writing) has popularized and interpreted Fuller's ideas and achievements. In his own right, Baldwin has been a figure in American designers' efforts to incorporate solar, wind, and other renewable sources of energy. In his career, being a fabricator has been as important as being a designer. Baldwin is noted as the inventor of the geodesic "Pillow Dome."
