"I read this article with interest and noted that Mr Glancey did not do his research - Chamberlin, Powell and Bon had a fourth partner; my father, Charles B Greenberg. He, too, was heavily involved in the Barbican. It took over his life from 1960 until he retired from active architecture practice. If Mr Glancey lived in one of the houses on the Barbican site he was in something my father designed. My father's involvement in the firm as a partner is often overlooked because he chose not to have his name added to the name of the firm - he maintained that Chamberlin, Powell, Bon and Greenberg did not have quite the same ring to it that the original name of the firm did. This results in what Mr Glancey did - my father's invisibility.
To say that the firm produced nothing much except Barbican is also incorrect. Towards the end of Barbican's building my father opened a branch of the firm in Honiton, Devon. There they produced a few developments. If Mr Glancey ever wants to increase his knowledge of what my father did in relation to Barbican and other Chamberlin Powell and Bon developments in the South West please get in touch.
