What's in a name: Firms' simplified family trees
Between January and December 1989, accounting historian Peter Boys prepared a series of simplified family trees showing the development of the big accountancy firms of the day.
The original trees from 1989 have been reproduced here with a series of textual updates from Peter Boys which have taken the story forward to May 2005, the 125th anniversary of ICAEW. Since then, the staff of the ICAEW Library & Information Service have added notes on further changes that have taken place.
