Evelyn Berezin

Pioneer of Real-Time Transaction Processing & Inventor of the Computerized Word Processor

Biographical Overview

Designed the world's first computerized airline reservation system (United Airlines Reservisor, 1962), operating across 60 cities with 1-second response time and 99.99% reliability. In 1969, Berezin founded Redactron Corporation and engineered the Data Secretary (1971), the first dedicated computerized word processing system, architecting custom MOS logic chips to automate text editing before the microcomputer revolution.

"There was no such thing as an off-the-shelf chip. We had to specify our own circuit designs, build our own MOS chips, and invent the architecture from scratch."

Historical Context & Impact

In short

When Evelyn Berezin designed the United Airlines reservation system in 1962, high-speed internet didn't exist. Her system connected 60 cities with 1-second query latency and operated continuously for 11 years with zero central processor downtime.

Key Technical Breakthroughs & Inventions

First Large-Scale Real-Time Airline Reservation System (1962) Designed the central logic and communication architecture for United Airlines' nationwide reservation system at Teleregister, linking hundreds of remote agent terminals across 60 cities to centralized dual processors with one-second query latency and virtually zero system downtime across a decade.

Automated Real-Time Financial & Banking Systems Engineered the electronic control logic for the American Stock Exchange automated quote system and the earliest automated bank teller account-balancing computers, proving the commercial viability of electronic real-time transaction processing.

The Data Secretary & Redactron Word Processor (1971) Founded Redactron Corporation in 1969 and designed the Data Secretary, creating the first standalone electronic word processing machine. Berezin designed custom 13-chip MOS LSI integrated circuits to implement dynamic line editing, margins, and magnetic tape/card storage.

Scaling High-Tech Hardware Manufacturing Grew Redactron from an independent startup to a publicly traded corporation with over 500 employees delivering thousands of word processing workstations worldwide, pioneering office automation years before IBM or Xerox entered the personal workstation market.
