I am sometimes invited to give lectures, but I usually have to say no simply due to lack of time. In case it is useful, below is a list of speakers who I have seen lecture and who I think are good (i.e., interesting and entertaining). I think that they are appropriate for a wide range of general audiences, but please contact them directly if you want to know if they are appropriate for your audience.
