After Bonaparte seized power, David hoped to be given responsibility for running government art policy himself; in 1800 he was offered the title of ‘painter to the government’ but turned it down, apparently because it lacked the powers that he wanted.

The range of work with young people

...systems that young people have are each other. ANDREW: I think if all the activities weren’t there and I didn’t have a penny to do an activity, the relationships would still be there, and the work would still go on. When we started The Factory Project out, we had 42 pounds in the bank, that was it, you know. And to set a project up on such a minimal amount of money...
