Today is late author and illustrator Roger Hargreaves’ birthday, and in honor of that fact Google has unveiled 16 new doodles, all of which are running today on the homepage.

British-born Hargreaves is of course the beloved author of over one hundred children’s books. His most famous books come from the Mr. Men and Little Miss series.

The stories are simple, funny and often times contain morals. Some of his beloved characters are Mr. Happy, Mr. Grumpy, Little Miss Sunshine and Little Miss Chatterbox.

Hargreaves’ books were a beloved part of my childhood, and millions more, as he has sold almost 100 million copies of his books worldwide. If you were born after 1975 or so and were not read these books as a child, you have terrible parents. Just kidding on that…but seriously. These books are crucial.

So this series of doodles is among my favorite Google doodles as of late. I also really loved the Charlie Chaplin doodle and the Earth day doodle. The recent royal wedding doodle was a little hard to discern, according to some.

Below are all 16 doodles. Hargreaves would have been 76 today.
