Jacob Ziv (Hebrew: יעקב זיו; born November 27, 1931 – died March 25, 2023) was a brilliant Israeli electrical engineer and information theorist. He is best known for creating important ways to make computer files smaller, called "data compression." He worked on these ideas with another scientist named Abraham Lempel. Their work helps us store and send digital information more easily every day.

About Jacob Ziv
Jacob Ziv was born in Tiberias, a city in what was then called Palestine, on November 27, 1931. He was very interested in how electricity and information work. He studied electrical engineering at the Technion – Israel Institute of Technology. He earned his first degrees there in 1954 and 1957. Later, he went to the Massachusetts Institute of Technology (MIT) in the United States. There, he earned his highest degree, a Doctor of Science, in 1962.
Ziv's Career and Contributions
After finishing his studies, Ziv worked in several important places. From 1955 to 1959, he was a senior research engineer for the Scientific Department of the Israel Ministry of Defense. He focused on creating new communication systems. While studying at MIT, he also worked at Melpar, Inc., doing research on communication theory.
In 1962, he returned to Israel. He led the Communications Division at the Israel Ministry of Defense. He also started teaching at the Technion – Israel Institute of Technology. In 1970, he became a professor there. He even served as the dean of the Faculty of Electrical Engineering from 1974 to 1976. He was also the vice president for Academic Affairs from 1978 to 1982.
Jacob Ziv also spent time at Bell Laboratories in the United States. This was a famous place for scientific research. From 1985 to 1991, he was the chairman of the Israeli Universities Planning and Grants Committee. This committee helps plan and fund universities in Israel. He was also a member of the Israel Academy of Sciences and Humanities from 1981 until he passed away. He even served as its president from 1995 to 2004.
Jacob Ziv passed away on March 25, 2023, at the age of 91.
How Ziv Changed Data Compression
Jacob Ziv is most famous for his work on data compression algorithms. An "algorithm" is like a set of step-by-step instructions for a computer. Data compression means making digital files smaller without losing important information. Think about how you might zip a file on your computer to make it easier to send.
The LZ Family of Algorithms
Working with Abraham Lempel, Ziv developed the "LZ family" of algorithms. The most well-known are LZ77 and LZ78. These algorithms find repeated patterns in data. Instead of storing the pattern many times, they store it once and then just refer back to it. This makes the file much smaller.
These methods are called "lossless data compression." This means that when you decompress the file (make it big again), it's exactly the same as the original. Nothing is lost. This is very important for things like text documents or computer programs.
Ziv's work is used everywhere today. It helps make JPEG images smaller, compress ZIP files, and even helps stream videos online. Without his inventions, our digital world would be much slower and take up much more space.
Awards and Recognition
Jacob Ziv received many important awards for his groundbreaking work. These awards recognize scientists who have made a huge impact.
Major Honors for His Work
In 1993, he was given the Israel Prize. This is one of the highest honors a person can receive in Israel. He won it for his contributions to exact sciences. In 1995, he received the IEEE Richard W. Hamming Medal. This award recognized his work in information theory and data compression.
He also received the Golden Jubilee Award for Technological Innovation in 1998. In 1997, he was given the Claude E. Shannon Award. This is a very prestigious award in the field of information theory. In 2008, he won the BBVA Foundation Frontiers of Knowledge Award for his work in information and communication technologies.
In 2021, Jacob Ziv received the IEEE Medal of Honor. This is the highest award given by the IEEE, a major professional organization for engineers. It was given for his fundamental contributions to information theory and data compression technology. He was also recognized for his leadership in research.
Ziv was also elected to important academic groups. He became a member of the American Philosophical Society in 2003. In 2004, he was elected to the National Academy of Sciences. These memberships show how highly respected he was by other top scientists around the world.
