@Speaking
If you would like to invite Lessig to speak, here's a guide:
Lessig's speaking agent is Chartwell Speakers. An inquiry about a non-academic, commercial event should be directed to Ellis Trevor at Chartwell.
Any invitation to a non-academic, non-commercial event (such as a political event) should be directed to Lessig's assistant. Her email is here.
Any invitation to an academic event should be directed to Lessig directly. Best email is this.
