Prof. Avraham Lampel passed away - the inventor who made the MP3 revolution possible Israel today


Professor Avraham Lampel was one of the inventors of the compression process in computers, which is still used today as a basis for the popular TIFF, PNG, ZIP compression technologies. Huge to Prof. Lampel for the opportunity to transfer a large amount of information in an economical and fast way

Professor Avraham Lampel, one of the inventors of the compression process in computers, which is still used as a basis for the popular PNG and ZIP compression technologies, has passed away.

and which also plays an essential role in PDF (for documents) and MP3 (for music) formats.

The world of computing and technology owes a huge debt to Prof. Lampel for the possibility of transferring a large amount of information in an economical and fast way.

Lossless compression

The biggest advantage of the LZ algorithm, which Lampel developed with Professor Yaakov Ziv, is that it enables the compression of information with minimal loss of important data without the need for prior knowledge of the type of information.

That is, the method can be run on many types of data files regardless of their content.

The LZ algorithm is the basis of many compression technologies used in computer memory devices, communications and other means and its influence still exists today in the field of giant technology companies and the billions of cell phone users in the world.

A milestone in the field of electronics and computers

In 2004, the International Association of Electrical and Electronics Engineers (IEEE) declared the Lampell-Ziu algorithm "a milestone in electronics and computer engineering".

The president of the union removed the lot from the sign indicating this, and it reads that "the algorithm for compressing information developed by Avraham Lampel and Yaakov Ziv in this place, in the years 1977-79, enables the transmission of information efficiently via the Internet. The algorithm made a significant contribution to the transformation of the Internet into an effective means of global communication." .

Huge impact on the world of computing

Also according to ACM, the most important association in the fields of computing and computer science, "the impact of the work of Professors Lampel and Ziv is so enormous that the current research in the field is still as vibrant as it was decades ago, and every year we see more theoreticians and applied researchers engaged in the expansion and development of the elegant idea that the two presented. It is not an exaggeration to say that the compression technologies that resulted from Lampel and Ziv's research accelerated the applications in mobile computing and multimedia and made them economically viable."

Completed three academic degrees in eight years

Prof. Lampel, born in Poland (1936), began studying at the Technion in 1959 and completed his three academic degrees in 8 years.

He taught electrical engineering and computer science at the Technion and in 1981-1984 served as the dean of the Taub Computer Science Faculty. In 1993 he was recruited to HP Laboratories and a year later he founded and managed HP Laboratories Israel. He was an IEEE fellow and a senior fellow at HP and the HP company registered eight Patents in the United States

Prof. Lampel has won dozens of prestigious awards and honors over the years, including the IEEE Golden Jubilee Award for technological innovation, the ACM Award for Theory and Application, the IEEE Hamming Medal and the Rothschild Award.

One of the greatest researchers of the Technion

The president of the Technion, Prof. Uri Sion, paid tribute to him and said that "the late Prof. Emeritus Lampel was a source of inspiration for all of us, and was among the greatest researchers that the Technion produced in its hundred years.

The Lempel-Ziu algorithm contributed to the world, free of charge, an unprecedented technology that enables the transfer of information quickly and without loss of information.

In his professional life, Prof. Lampel embodied the connection between deepening in basic science and excelling in applied research.

There are few researchers whose research has had such a wide impact on technological progress and our daily lives.

Of blessed memory".
