So you want extend a speaking invitation to Daniel. . .
Daniel is always pleased to receive speaking invitations, but before extending any invitation, please read this letter from him:
On my 75th birthday I gave myself the present of a promise -- a promise never again to journey to distant speaking engagements. Not that I didn't enjoy the many I actually have made (at least in memory if not in fact). But travel has never been something I enjoy, and post 9/11 airline travel I enjoy even less.
BUT! I have something ever better to offer in its place. Instead of journeying to a school of any kind (high school, college, or university), I will be more than happy to meet with individual classes in which any of my books have been used. Instead of addressing a crowd of dozens or hundreds, with little or no interaction, I prefer the opportunity of interacting with students on a one-to-one basis by way of a telephone conference. And you can be sure that students get a whole lot more out of this than they would listening to a speech in an auditorium. From the many classroom telephone conferences I've had in the past I know this for an undoubted fact.
And I'm happy to meet with as many different classes as are involved with my work -- whether it's one or ten (not all on the same day, of course). I'm perfectly willing to work with each teacher individually to set up appropriate dates and times.
And no fees are involved. So you save money, I save travel time, and your students gain a kind of access to me that they couldn't possibly have otherwise.
