Google’s latest doodle features a familiar cat and grin.

The tech giant is paying tribute to Sir John Tenniel, the illustrator behind the classic fictional characters of Lewis Carroll’s renowned novels, “Alice’s Adventures in Wonderland” and “Through the Looking Glass” on his 200th birthday anniversary.

Tenniel, born in London in 1820, gained fame as an artist at the age of 16. He submitted his first body of work, an oil painting, for an exhibition at the Society of British Artists. Tenniel went on to become a political cartoonist for a weekly magazine, Punch, in 1850. It was there he developed his unique style accompanied by his photographic memory.

Tenniel’s talent caught the attention of Charles Dodgson, known to the world as Lewis Carroll, after an introduction in 1864. He would later go on to illustrate “Alice’s Adventure’s in Wonderland” released in 1865, followed by “Through the Looking Glass” in 1871. Tenniel then resumed his work as a political cartoonist with Punch.

His contributions to “Alice in Wonderland” and Punch were honored in 1893 with a knighthood award.

Today’s Google doodle was created by Matthew Cruickshank. The North London illustrator said he was inspired by the Cheshire Cat and Alice’s conversation.

“I hope people are inspired to be as imaginative as Tenniel was with his work,” said Cruickshank in a statement.
