Louan Gideon (November 12, 1955 – February 3, 2014) was an American actress best known for her role as antagonist Danielle Atron on Nickelodeon's "The Secret World of Alex Mack". She was also the last actress to play Liza Walton Sentell on the long-running soap opera "Search for Tomorrow".
Louan Gideon is dead.
The context mentions that Gideon lived from 1955 to 2014. Gideon is therefore dead at any time outside of that range. It is 2019, which is outside of that range. Therefore, Gideon is dead. This is further evidenced by the past-tense used in the context: "was". The AI probably had difficultly because it was not explicitly mentioned that she was dead. Rather, it was inferred based on common time period notation and past-tense phrasing.
