Steven Quincy Urkel is presumably born around this time in Illinois. Details of his very early childhood are scarce, but it's suggested he was an intelligent but socially awkward child from the beginning.

Steve's parents, Carl and Rachel Urkel, are rarely seen or mentioned in detail throughout the series. Carl is later revealed to be a rocket scientist, providing a partial explanation for Steve's intellect. The circumstances surrounding their eventual departure remain unclear.

Steve Urkel makes his iconic debut, initially intended as a one-off character. He crashes Laura Winslow's date with a persistent and clumsy pursuit, immediately establishing his signature quirks.

Due to overwhelmingly positive audience response, Steve Urkel quickly transitions from a guest role to a recurring character, and then a core cast member. His unrequited love for Laura Winslow becomes a central plot point.
