Analysis of information sources in references of the Wikipedia article "Joseph Eichler" in English language version.
After attending New York University and marrying Lillian Moncharsh in 1925, he relocated to Northern California, where he worked as a food broker for his father-in-law's wholesale dairy business for the next 20 years.
When Eichler married Lilian Moncharsh – whose family owned a butter and eggs wholesale firm – he eventually worked for his in-laws and joined the competitive food industry. In 1940 Eichler moved with his wife and two sons to California so that he could assume the position of treasurer of the San Francisco-based family business.
