The Big Bang Theory Wiki

Joshua "Josh" Wolowitz is Howard Wolowitz's younger half-brother. In "The Fortification Implementation", Howard meets Josh, his father's son from his second family, for the first time. Josh is an oceanography student from San Diego; learned about Howard after his mother's lawyers contacted him.


Season 8[]

Josh first appears in "The Fortification Implementation" at Howard's late mother's house, into which he and Bernadette have moved. He tells Howard that a lawyer contacted his father, Sam Wolowitz, about the title on that house. As Sam was Howard's father, this young man is Howard's younger half-brother. Howard calls Bernadette to report that weird things are happening.

Howard runs off to get more coffee, leaving Josh with Bernadette and Raj. Josh is an oceanography student in San Diego; while Bernadette comments that she loves Finding Nemo. Raj challenges him as to who he really is, though who would still claim to be a Wolowitz? Does he want money, a kidney, or for Howard to replace his father as Ringo in a Beatles cover band? Bernadette decides to send him after Howard. Raj tells Josh that he wanted to hear about Josh's studies, since they sounded cool.

Howard is upset and uncomfortable that Josh has appeared, as it means that his father went on to have another family after he deserted Howard and his mother. As Howard gears up to tell Josh to leave, Josh sees Howard's astronaut portrait and excitedly exclaims that he can't believe that his brother was an actual astronaut! He states that it's amazing and asks what space was like. Raj tries to tell Josh that it's time for him to hit the road, but a flattered Howard cuts him off saying "Whoa, hey, hey. The young man asked a good question," and starts to tell his now-known brother about the greatest adventure of his life.

Josh visits his father's other family.

Howard is entertaining Josh with magic, which he finds pretty cool, until he figures he has to go. Howard hopes to see him again, and Josh states that he hopes to see him again as well, as he had always dreamed of having a brother to play catch with; Bernadette tells him to keep dreaming. Howard mentions throwing a pitch which impresses Josh, but Bernadette states Howard used a robot that he made to do it, and Josh thinks she means sex, which Howard denies but Raj confirms.

At the door, Josh asks Howard about the robot, and Howard tells him it was just a mechanical hand. Josh thinks that that is all he needs and Howard hugs him telling Josh that he is definitely his brother.

Josh doesn't make another appearance, nor is he ever mentioned again on TBBT.


At first, the meeting Josh had with his older half-brother was awkward but it got better as Josh thought it was amazing to have a brother who was an astronaut.

It is shown he has a warped manner similar to Howard's before he met Bernadette. He understands about the robot arm that Howard used for self-gratification which causes Howard to hug him in acceptance, knowing that he is really his brother.
