body: The book is *On growth and forms* by D'arcy Thompson. It was published in 1942 and Thompson died in 1948. Wikipedia uses the image citing public domain. Can I use extracts and images from the book with proper citation without the problem?
  
  
  The image I want is Fig. 125 on [this page.](https://archive.org/details/ongrowthform1917thom/page/322)
  
  
  The book is also available in archive.org and I think it should be in public domain. 
  
  
  The image itself has a caption and in bracket says `(After Rhumbler)`, I am not sure if it is by Thompson himself. Rhumbler would be Ludwig Rhumbler who died in 1939. So it should still be in the public domain as far as I get it.

  Do I need a copyright license for the image or it is in the public domain and I could use it without one?
  
  
  I am in Germany and my thesis will be published in Germany.
