Starting soon after World War II, the Institute embarked on the publication of the fascicles of the "Atlas of Tumor Pathology," in conjunction with the Division of Medical Sciences of the National Research Council and, specifically, the Committee on Pathology and its Subcommittee on Oncology.

In addition to being a member of the Board of Regents of Vanderbilt University, his alma mater. Dr. Henry was also one of the consultants in the preparation of the third edition of "Webster's New International Dictionary." Within a brief period of 2 years.
