Tom Weldon was brought up in London. He studied history at Oxford University and then was hired as a graduate trainee by Macmillan. After three years as a nonfiction commissioning editor, he joined William Heinemann, then owned by Reed Elsevier. He spent nine years there as an Executive Editor; American Editorial Director, based in New York, and then as publisher of the imprint.
In 1997 he moved to Penguin as Publishing Director of Michael Joseph. In 2001 he became Managing Director of the Penguin General division then comprising the Michael Joseph, Viking, Hamish Hamilton, Fig Tree, and Penguin Ireland imprints. He was made Deputy CEO of Penguin UK in 2009 and CEO in 2011.
In July 2013, he was appointed the first CEO of Penguin Random House UK.
Tom has also attended London Business School. From the age of nine, Tom has had a passion for horse racing. In his view, gambling is very important to publishing as well. He does not find it surprising, therefore, that he fell in love with publishing on his first day at Macmillan, and that love has never gone away.
