Dr. Louis Donaldson was a member of the Black Mesa Science Team involved in the research of creatures from Xen, prior to the Black Mesa Incident. During his work, he became the discoverer of the Barnacle creature, but unfortunately, he also became its first victim. The Barnacle's full name, Cirripedia donaldsonia, was subsequently named after him.[2]
