A boldly illustrated and fascinating collection of profiles featuring the women and men who were pioneers of science, technology, engineering, the arts, and mathematics.

You likely know that Mae Jemison was the first African American woman in space. And maybe you know that Jane Goodall was the first human accepted into a chimpanzee community. But you might not know that Alan Turing was the first person to introduce the concept of artificial intelligence. Or that Tu Youyou was the first Chinese woman to win a Nobel Prize.

Who Did It First? 50 Scientists, Artists, and Mathematicians Who Revolutionized the World brings together all of these trailblazers into one stunning package. With both well-known figures and lesser-known heroes, editor Alex Hart, writer Julie Leung, and illustrator Caitlin Kuhwald celebrate the inspiring innovators who braved uncharted waters to pave the path for future generations.

Perfect for fans of Little Leaders, Women in Science, and Rad Women Worldwide, Who Did It First? makes a wonderful gift for any occasion and is a must-have for every young reader's library.

Featuring Ada Lovelace, Mindy Kaling, Temple Grandin, Maria Tallchief, Riz Ahmed, and many others.

Most favorite
Color: Red, Size: Medium
My fur babies love these balls they are their favorite. Any size dog can play with it because of how it's made. it easy to play with. It's made with a lot of opening and is made of a soft rubber. My Shepherd pup and Boston's love to play with it, and I had to buy 3 so they don't fight over it. The giggler will break easy and even the first day on rough riders, but they can still enjoy the ball itself even without the giggler. It size is about 4in. If Amazon gave halves Id give it a 3.5 because of the giggler breaking so easily but otherwise my girls still love this ball.

Wonderful toy, but for most dogs it's a toy you play WITH dog, not a chewie
Color: Red, Size: Medium, Color: Red, Size: Medium
I'm a dog trainer, and have shared my life with many dogs. For the current mini aussie, toys are a necessity and a lifeline. He is tough on toys, and we have certainly tossed many many MANY ruined toys. This toy is wonderful: the squeak is fabulous, it bounces great, it's easy to carry around, and great for fetch and a little tug. Love it, and so does he. But it's soft rubber, so it's a toy to be played JOINTLY with... not a chewie. It will create a lot of fun times and silly entertainment and exercise, but I will put it away when I am not closely monitoring and involved with the play. One of the photos is blurry but shows that the rubber is soft.

Stops giggling after a few weeks
Color: Red, Size: Medium
I have bought three of these Giggler toys. The dogs absolutely LOVE this giggler toy and it's irresistible to them, even more so than squeaky toys. The rubber is soft and flexible, and after weeks of tug-o-war between dogs, the rubber has stood up well and is showing no sign of breakage. However in two of the toys, the giggler mechanism has started to fail and barely makes any noise at all. The dogs have lost interest in them.

A winner!
Color: Red, Size: Medium
Our pembroke welsh corgi’s favorite toy. We ended up getting him a second one. One for inside. The other, outside. Great for tug-a-war, fetch, and just chewing on. I can recommend this all day long.
