Christy Mathewson is the primary pseudonym of American voice actor Edward Davies Eddie Frierson, who was born on November 22, 1959, in Akron, Ohio. He adopted this alias for his voice work in anime and other projects, a name inspired by his acclaimed one-man stage show about the legendary Baseball Hall of Fame pitcher, Christy Mathewson. The alias is sometimes misspelled as Christy Matthewson, and he has also worked under the names Ted Richards and Eric Frierson, the latter originating from a misspelling of Eddie in the credits of some 1980s anime productions.

Frierson has been active in voice acting since the 1980s and is particularly well-known for his extensive contributions to English dubs of anime. As the user notes, he provided the voice for Kai Shiden in the Mobile Suit Gundam movie trilogy, a role that stands as a significant credit in his filmography. His other prominent anime voice roles include Eledore Massis in Mobile Suit Gundam: The 08th MS Team, Makoto Mizuhara in various El-Hazard projects, and Yakumo Fujii in the Streamline Pictures dub of 3x3 Eyes. He also voiced Ken in the Gatchaman OVA, Atori in Noein, and Louis Nichols in Robotech: The Shadow Chronicles. His work spans a wide range of series, with additional credits in Cowboy Bebop, Digimon Adventure, Fist of the North Star, Naruto, and many others, often in supporting or additional voice roles.

Beyond anime, Frierson's voice can be heard in numerous Western animated features and live-action films. He has contributed additional voices to major releases from studios like Disney and Sony Pictures Animation, including Wreck-It Ralph, Frozen, Tangled, Hotel Transylvania, Cloudy with a Chance of Meatballs 2, and Chicken Little. He also provided character voices for live-action films such as the skunk in Doctor Dolittle and Commander Aldrin in Fly Me to the Moon. In the realm of live-action television, he voiced several monster characters for the Power Rangers franchise, including Frax in Power Rangers Time Force, as well as roles in VR Troopers.

Away from the microphone, Frierson has enjoyed a distinguished career in theater. He is the writer and star of the one-man show Matty: An Evening with Christy Mathewson, a performance for which he has won Drama-Logue Awards for both acting and writing and has been performed at the National Baseball Hall of Fame. His classical stage work includes roles such as Horatio in Hamlet and Flute in A Midsummer Night's Dream, and he is a co-founder of the Nevada Shakespeare Festival. His theatrical performances have earned him additional accolades, including a New England Drama Critic's Award and the Maurice Scott Award for Los Angeles theatre.
