Arthur-ZangArthur Zang (1987–)

What He Invented: The Cardiopad.

Why It’s Important: The Cameroonian engineer invented the Cardopad, a touch-screen medical tablet that enables heart examinations such as the electrocardiogram (ECG) to be performed at remote, rural locations while the results of the test are transferred wirelessly to specialists who can interpret them. The device spares African patients living in remote areas the trouble of having to travel to urban centers to seek medical examinations.

What He Invented: A Shoe-Lasting Machine.

Why It’s Important: Matzeliger, who was from Suriname, invented a shoe-lasting machine that increased the availability of shoes and decreased the price of footwear. Matzeliger’s shoe-lasting machine increased shoe production tremendously. The result was the employment of more unskilled workers and the proliferation of low-cost, high-quality footwear for people around the world.
