List of Missouri University of Science and Technology alumni

It is named for Karl Hasselmann, a 1925 graduate in mining engineering, who had a prominent career in the oil industry.

The listed alumni span multiple fields and careers, particularly those concentrated in science, technology, engineering, and mathematics.

The creator of Twitter, Jack Dorsey, enrolled at Missouri S&T in 1995 majoring in computer science and mathematics, but transferred out during his junior year to accept a job with the New York-based company Dispatch Management Services after hacking into their computer network and alerting the company chairman of a hole in their software.

[5] Many notable NASA astronauts and engineers are graduates from Missouri S&T, such as Sandra Magnus, who was aboard the last American Space Shuttle, and George Mueller, who helped enable the Apollo 11 Moon landing.

Other S&T alumni have filled leadership positions within state and federal government, and some have become known in athletics and entertainment.
