She filed a patent for an 'Electronic data file processor,' an early system for processing electronic data files.
On March 15, 1957, Evelyn Berezin filed U.S. patent application US 3,017,610, titled "Electronic data file processor." This invention addressed the emerging need to store, organize, and retrieve electronic data files efficiently, a challenge central to the growth of business computing in the late 1950s.
As companies increasingly sought to automate record-keeping, Berezin's data file processing designs offered practical solutions for managing large volumes of information electronically rather than relying on paper ledgers and punch-card systems alone. Her work in this area anticipated the database and file-management technologies that would become ubiquitous in later decades.
This filing represents a key milestone in Berezin's transition from calculator-focused inventions toward broader information-systems architecture—a trajectory that would define the rest of her career. It reflects her growing expertise in handling structured data electronically, skills she would later apply directly to her celebrated designs for airline reservation systems and, ultimately, the Data Secretary word processor. As a woman engineer navigating a field with few female role models, Berezin's steady stream of patents in this period quietly built the technical foundation for innovations that would transform modern offices.
