Josiah Willard Gibbs (11 February 1839 - 28 April 1903), an American physical chemist.
This file was taken from w:en:Image:Willard Gibbs.jpg, which was given by w:en:User:Reddi at the time of 06:43, 29 Aug 2004. The image seems a copy of the widely circulated portrait of the physical chemist.
In the English Wikipedia, the image is described as "19th century photograph. public domain" with the copyright tag {{PD-old}} (the English Wikipedia version), which calls a statement that this image is in the public domain because its copyright has expired in the United States and those countries with a copyright term of life of the author plus 100 years.
User:YebisYa, who uploaded the file to Commons, has not specified who took the photo, and when and where it was published, but believes that it was anyway taken and published somewhere in the USA on or before 1903, and qualifies at least for the copyright tag {{PD-Art}} (Commons version).
