Copy of a cover page for an electroencephalograph (EEG) test performed on Jack Ruby by EEG Laboratory in Dallas, Texas on January 28, 1964.

The left side of the page shows a handdrawn illustration of the top of a human head, numbered one through ten. The left corner of the cover page has "pages 010 \ thru 317" handwritten with what looks like Jack Ruby's signature below. There are five other individual's signatures below this - "Sheff D. Olinger MD"; "John T. Holbrook MD"; "R. J. Weaver Deputy Sherriff Dallas Co."; "Robert L. Stubblefield MD"; "Dr. L. Towler".

The pre-printed text in the center of the cover page is as follows:
"EEG Laboratory

Age____________52 [handwritten]_____________

Mrs. Joan Weiberg (?)".

Text filled out for numbered, pre-printed form within outlined box indicates that the test was recorded at 10:50 A.M.; the patient came in walking and was alert but drowsy and cooperative; that the patient is right-handed and his last meal was at 8:38 A.M. that day; and the patient was on no medications. In the background of the right half of the page is what looks like lines from an EEG recording.

The names on this page refer to the following individuals: Dr. Sheff Daniel Olinger, Jr.; Dr. John T. Holbrook; Dr. Robert Stubblefield; Dr. Martin L. Towler; Dallas County deputy sheriff Robert J. Weaver and Mrs. Joan Weiberg (it is unknown exactly who this individual is).

This object was originally part of the evidence collected by the Dallas County District Attorney’s Office and specifically prosecutors Henry Wade and Bill Alexander during the investigation leading up to the Jack Ruby trial for the murder of Lee Harvey Oswald.
