In 1977, with his colleague Professor Yaacob Ziv, Lempel published LZ7, the first version of the Lampel-Ziv algorithm, and in 1979 the second version, 79LZ.

Discover how this powerful algorithm measures randomness and compresses data—perfect for tech enthusiasts and curious minds alike!

Mr. Zib on the left, Mr. Lempel on the right. Ziv and Lempel released the first version of the LZ algorithm, LZ77, in 1977. After that, in 1979, the second version, LZ79, was released.

He, alongside Professor Avraham Lempel, who died in February at the age of 86, developed the data compression algorithm Lempel-Ziv (LZ), which paved the way for the development of the ZIP, PDF ...
