Andrew Ryan is the founder of Rapture and owner of Ryan industries. He is a brilliant Russian scientist who fled  from his communist government, believing that the people who ruled were unworthy of being in charge. He called those who were of weaker class "parasites" due to the belief that they relied on the upper classes to sustain them. He then fled to America in pursuit of a government that could rule in his expectations. He was devout to this new country, until the State-Run Social programs of the 1930's tested his devotion. Ryan despised Socialism and Collectivism.  However, the final straw that made Ryan despise America's government was the atomic bombs on Hiroshima. It was the polar opposite and the antagonising force of his ideals. Ryan's philosophy was 'one could own what one earned'. To make this Philosophy come into the reality... He built Rapture to create a community where "The artist will not fear the censor, where the scientist would not be bound by morality, where the great will not be constrained by the small."  His city was finished in 1948 with great prosperity. It was the paradise he dreamed of... Until he found himself in a Civil War that destroyed that paradise... With just the will of one man.

Andrew Ryan is one of the most important characters in "Attack on Rapture." He is one of the most powerful men in Rapture. Having his connections with the Jaeger family who were one of the ones who pioneered numerous science in Rapture. His relationships with the Ackermans has gotten him loyalty from their members, but also made numerous enemies with the forces of Fontaine and a few others. Being the powerful and inspirational ruler of Rapture, he has to sound firm and commanding when giving his speeches and orders. He is also a man who is almost always in thought. So sound philosophical and sophisticated when speaking and making a internal monologue. It helps to look up cutscenes and audio diaries on his character to find a voice for him.
