He joined the R&D department of the company and worked on various projects which allowed him to start a subsidiary company of Vernmangus.  It was called Penrod Incorporated and built commercial air and spacecraft that catered to economy fliers that weren’t wealthy enough to own such crafts or travel first-class.  Also, the crafts proved popular with carriers smaller than the big ones that transported sometimes over a million passengers everyday.  Economy fliers appreciated what Hiram offered and he filled a niche that larger companies didn’t want to fill. 

For thirty years, Hiram built his company from the ground up.  He had an R&D department that often lent its expertise to help different companies.  Thanks to the department, Penrod Incorporated grew fast and by the 1890’swas worth well over $1 billion in ths dimension. 

During that period, his father and mother died.  He attended the funerals but only in the dimension adjacent to this one.   He couldn’t be seen and did manage to speak with their spirits.  They had long changed their attitude toward him.  But by then he was so successful and so busy that he didn’t have time to return home.  He heard his mother say she loved him.  But his father never admitted it even after he was dead.  But Hiram sensed that he was proud of him when he told the dead man that his company was worth more than some of the largest companies in this dimension. 

By 1900, the factory Hiram’s father had started was a museum.  It was sold to the state of Vermont by the person who had bought it from Hiram’s father a couple years before he died.  Hiram visited it a few times and amazed people with his knowledge of the company that at one time produced the uniforms soldiers wore during the Civil War.  He even contributed $100,000 for the upkeep of the museum and established the Penrod Trust to keep it from falling into disrepair.  He may not have been allowed to work there after the war due to his physical condition at the time.  But it didn’t keep him from saving it from the wrecking ball.  Even after he died in 1938 the Penrod Trust kept it open for future generations to enjoy thanks to the InterdimensionalEmployment Agency giving him a chance to make a fortune he shared with the factory museum.
