). Although he intended to establish a patent model museum, the
stock market crash of 1929 damaged his fortune; the models were left in storage. After his death, the collection went through a number of ownership changes; a large portion of the collection—along with $1,000,000—was donated to the nonprofit United States Patent Model Foundation by Cliff Petersen. Rather than being put into a museum, these models were slowly sold off by the foundation. Much legal wrangling, purchasing, and re-selling ensued.
A comparatively small number of models (4,000) were the property of the Rothschild Patent Museum until 2015, when they were transferred to
