Hungarian mathematician János Bolyai

Comment: "The picture of him is taken from a stamp issued by the Hungarian Post Office to celebrate the centenary of his death. It is not believed to be authentic and no authentic picture exists." cited from J J O'Connor, E F Robertson: János Bolyai, The MacTutor History of Mathematics archive, March 2004


Public domain This image (or other media file) is in the public domain because its copyright has expired.

This applies to the United States, Canada, the European Union and those countries with a copyright term of life of the author plus 70 years.

Note that a few countries have copyright terms longer than 70 years: Mexico has 100 years, Colombia has 80 years, and Guatemala and Samoa have 75 years. This image may not be in the public domain in these countries, which moreover do not implement the rule of the shorter term. Côte d'Ivoire has a general copyright term of 99 years and Honduras has 75 years, but they do implement that rule of the shorter term.

The picture is from [1]. The "Copyright information" at the bottom of the page says: "We believe that most of the images are in the public domain" which is good enough for me.
