Interestingly neither author was a clinician. Todd's successor as Director of the Brush Foundation Study was Greulich who held the post from 1940-1949 2. Approximately 800 children from affluent families in Cleveland, Ohio, were x-rayed for the study by 1930 3. The study continued to perform x-rays of its subjects for 3-month to 1-year intervals. This research study collated large amounts of data on skeletal development by fastidiously-performed serial x-rays of its enrolled subjects, some of whom were first radiographed at the age of three months. The material in the Atlas was from the Brush Foundation Study of Human Growth and Development, established by Thomas Wingate Todd (1885-1938) 3 in 1929, at Western Reserve University School of Medicine. It also remains an important volume for those in forensic fields. Although an old text, which has been reprinted multiple times over the intervening years, many departments of radiology around the world still rely on tattered old copies of this slim volume.

The Radiographic Atlas of Skeletal Development of the Hand and Wrist by WW Greulich and SI Pyle is a classic radiological text that was first published in 1950.
