September 13 1998 marked the 150th anniversary of the accident to Phineas Gage, one of the most famous cases of survival after massive injury to the brain, and certainly the most famous case of personality change after brain damage. For this article a sample of the current literature about Gage was examined. It was found that although his case is mentioned in about 60% of introductory textbooks in psychology, there is a good deal of inaccuracy in what has been written about him. Similar inaccuracy was found in a smaller sampling of the psychiatric, medical, physiological, linguistic, and general neuroscientific literature. The main basis of the inaccuracies is an ignorance or disregard of what is contained in the primary sources about Gage, coupled with a tendency to attribute to him characteristics that belong to other cases of frontal damage. The errors and their bases are discussed in an endeavour to restore the picture of Gage to its original state. The paper includes an Appendix of verbatim quotations from the primary sources that can be compared with the later, inaccurate renditions.
