Logan Frazee (28 June 1939 – 24 July 2013; age 74)[1], also credited as Logan Z. Frazee, was a special effects assistant on Star Trek VI: The Undiscovered Country, Star Trek Generations, Star Trek: First Contact, and Star Trek: Insurrection. In this role, he made artificial effects used to create illusions in the films. These were effects produced on the set, as opposed to those created in post-production known as "visual effects."
Logan and his brother, special supervisor/coordinator Terry Frazee, were both sons of the special effects pioneer Logan R. Frazee.
