Gerber’s thorough research is based on an impressive range of hitherto unpublished sources – drawn from some 25 archives, scattered over 3 continents – as well as much privately held material which includes Deissmann’s personal diary. An important added feature of this source-rich work is the substantial collection of relevant appendices and addenda, as these consist of transcribed documentary material that would otherwise remain largely unknown or inaccessible to most readers.
