Q1: How long did it take you to write the book on Linke?

A: It is impossible to calculate accurately. I came up with the concept in 1981 but it only became possible to start seriously in 1997. However, because of the lack of information about Linke's early work, the book was only going to cover the period from circa 1900. It was only in 1999 that I was able to track down the first Linke daybooks that he kept in his pocket that I was able to start with any real confidence.
