Events
Right after the inauguration of Black Mesa, only a handful of scientists were hired to work on the back then smaller installations. Ivan was a weapons research scientist and KGB agent from the cold war that infiltrated the facility as a new employee but ended up going AWOL after seeing that alien life existed, an event that would change anyone's perspective. His true identity was never discovered by Black Mesa.

As Black Mesa gained traction in the war against Aperture Science, contracts flowed in and money went up. The installations started to be upgraded, but eventually the change was so fast and abrupt that entire new sectors were needed to be built, and the old ones decomissioned and closed, used only for storage.

Ivan, working at the soon to be decomissioned "X-Lab", was too fond of his new invention, the HEV suit MK I, but due to his temper his project partner Dr. Cross (father of Gina Cross) and other few scientists took advantage of the new administrator in charge Wallace Breen and convinced him to fire Ivan and many other older employees and start hiring new fresh young minds to fill the new sectors being built.

Ivan poisoned Dr. Cross with a radioactive material and was given a life sentence, where his true identity was discovered during a thorough background check and was court martialed, sent to military prison, which was under the surveilance of the S.C.I. of course.

In there he developed his insanity further and was diagnosed to also be poisoned with deadly amounts of the same radiation. He had no choice but to join the experiment at Sven Co-op where his skills could be needed... if he survived.
