Dear Mr./Mrs./Miss/Dr. <last name>,

Thank you for taking the time to meet with me last <day of week/time of day/month/date; e.g., Tuesday morning, June 28>. I enjoyed speaking with you and feel that you added substantially to our understanding of the Skinker-DeBaliviere neighborhood, as well as of St. Louis life.

As we discussed, the audio tapes made of our conversation will be eventually deposited at the Missouri Historical Society's Library and Research Center for public research. If you have any questions or concerns about the audio tapes, or if you feel you have more to add, please call me at <your phone number>.

Again, thank you for the time you generously devoted to the interview, the interest you showed in our project, and your insights into and memories of the Skinker-DeBaliviere neighborhood.

Respectfully,

<your name>
