Inventory of Material
from the Files of the Late Dr. Olavos T. Fontes

When Dr. J. Allen Hynek visited Brazil, he met with the widow of Dr. Olavos Fontes.  She gave Dr. Hynek a number of files, mostly of articles in English, which Dr. Fontes had prepared either for publication in his own little newsletter, The Brazilian Flying Saucer Review, or for the APRO Bulletin.  Also included were a few letters to correspondents in the U.S., Coral Lorenzen, Director of the Aerial Phenomena Research Organization (APRO), Prof. Charles P. Maney, Defiance College, Ohio, and Alexander Mebane of Civilian Saucer Intelligence in New York (CSI-NY).

On his return to the United States, Dr. Hynek split the file into two parts.  He gave one portion to Dr. Willy Smith and the other portion to another researcher.  Dr. Smith has recently donated his files to the Sign Historical Group.  An inventory of the Fontes related material contained in the donated files appears below.  The material which originated with Dr. Smith is indicated by (#).  A small amount of other Fontes reports and manuscripts have been found in the files of other researchers.  Links found on the Internet that involve Fontes or the cases he wrote about are also provided. 

An addendum of Brazilian UFO cases found on the Internet is also included to demonstrate the character of reports from this South American Country.

Serial numbers on various cases (U-xxx or M-yyy) were assigned by Dr. Smith.  The letter "U" indicates that the case was part of the UNICAT, a database of outstanding UFO reports in Dr. Smith's opinion.  The letter "M" indicates the serial number for the MAYBECAT which contained cases Dr. Smith thought might be interesting if more data or results of investigations became available.  Dr. Smith said that very few cases were upgraded from the MAYBECAT to the UNICAT.

The Sign Historical Group would welcome additions to Fontes collection either by donation or exchange.  Contact: Sign Historical Group, P. O. Box 391, Canterbury, CT 06331 or e-mail:
