From an AP obit headlined “Author Ian Falconer of ‘Olivia’ books for children dies”:

Author and illustrator Ian Woodward Falconer, known for his “Olivia” book series for children, has died.

Falconer’s lawyer and agent Conrad M. Rippy said Falconer died Tuesday of natural causes while with family in Norwalk, Connecticut. He was 63.

Falconer’s “Olivia” books featured a clever piglet with a great imagination named Olivia, a character he developed for his young niece in 1996. Family members and friends encouraged him to keep working on the character.
