(written from a Production point of view)
Jon Steuer (born 27 March 1984; age 29) was the first actor to portray Alexander Rozhenko, Worf and K'Ehleyr's son, in the Star Trek: The Next Generation fourth season episode "Reunion" in 1990. For the remainder of the episodes on TNG featuring Rozhenko, he would instead be played by Family Ties star Brian Bonsall. Jonathan Frakes mentioned that Steuer "was too shy, not a warrior. Probably the reason why he was recast". ("Departmental Briefing Year Four - Production", TNG Season 4 DVD special feature)
Born as Jon Paul Steuer in Escondido, California, his acting career lasted for less than a decade. In 1989 he worked on an episode of Day by Day. He appeared in the 1991 film Late For Dinner with Tim Kelleher and Jeremy Roberts.

Steuer acquired his most recognition as an actor for playing Quentin Kelly on the situation comedy series Grace Under Fire. During his time on this series, Steuer worked with such Star Trek alumni as Rickey D'Shon Collins, Paul Dooley, Monte Markham, Penny Johnson, Cristine Rose, Heidi Swedberg, and Ken Thorley.
