What pen names did William Makepeace Thackeray use for his early work?

For his early contributions to publications such as Fraser’s Magazine, The New Monthly Magazine, and Punch, the British author William Makepeace Thackeray frequently used several pen names rather than his own. These pseudonyms included:

• Mr. Michael Angelo Titmarsh1
• Fitz-Boodle1
• The Fat Contributor1
• Ikey Solomons1

Thackeray later collected many of these early writings, which featured works like The Yellowplush Correspondence and The Luck of Barry Lyndon (later revised as The Memoirs of Barry Lyndon), into a four-volume set titled Miscellanies.1
