Linda Liukas (born 1986) is a Finnish children's book author, illustrator and an instructor for beginner programmers.

In 2001, she made a page in Finnish about Al Gore, hoping to show him how much she admired his values, not to mention his looks.

For the next ten years she studied philosophy, business, French and engineering but maintained an interest in programming.

"[7] Initially Ruby was a side-line Liukas created for herself drawing sketches of the little red-haired girl encountering a snow leopard or sorting out problems with penguins and green robots.

When Liukas showed her approach to her friends, they encouraged her to publish the illustrations and explanations in book form.
