Dan Tyler Moore Jr. was an American intelligence officer, SEC regional commissioner, businessman, public speaker, and author.

Moore then went to Cairo as a Deputy to James M. Landis, Head of the Economic Mission to Middle East,[4] but also with a secret duty as a regional chief for the OSS.

Subsequently, he published several non-fiction books, including Cloak & Cipher (1962, with Martha Waller), Wolves, Widows, and Orphans (1967), and Lecturing for Profit (1967).
