William English, one of the inventors of the computer mouse, died of respiratory problems late last month at the age of 91, reports The New York Times Monday. English built the very first mouse after the concept of his colleague Douglas Engelbart.

His first design was based on two voltage dividers that respond to the movement of the mouse. The computer mouse was created in combination with software that shows the cursor on the screen.

English called the device a mouse, because the cursor on the screen was named CAT. Although he intended to come up with another name for it, it never changed.

In addition to the computer mouse, decades ago English and Engelbart also explored concepts that we still use today, such as video calling and hyperlinks.
