From Oliver Heaviside: Sage in Solitude (ISBN 0-87942-238-6), p. 120. This is a reproduction of a steel engraving originally published in The Electrician, 1896. It was scanned on an Epson Perfection 1250 at 400dpi, cleaned up (some text was showing through the back) in Photoshop, reduced to grayscale, and saved as JPG using the 'Save for Web' optimizer.

The two-dimensional work of art depicted in this image is in the public domain worldwide due to the date of death of its author (if it is was published outside of the U.S. and the author has been dead for over 70 years), or due to its date of publication (if it was first made public in the U.S. before 1923). Therefore this photographical reproduction is also in the public domain, at least in the United States (see Bridgeman Art Library v. Corel Corp.), in Germany, and in many other countries.
