"Prof. Abraham Lempel, Inventor of PDF & MP3 Compressions"

I never ever heard about Lempel being involved in MP3 development. So I checked Wikipedia on MP3: It names 6 developers, none of them being Lempel. "And others", says the list, with a link: "Lempel" is not found on the referenced page. Lempel certainly did not develop the primary, psychoacoustic (and lossy) compression method of MP3!

I also never heard of Lempel developing PDF, so I checked Wikipedia on PDF as well, including the "History of PDF". No mention of Lempel in either article.

The Wikipedia article on Abraham Lempel makes no mention of neither MP3 nor PDF.

Lempel and Ziv (and Welch) did some tremendous work in developing the most influential lossless compression algorithm of all times. The importance of this should most certainly not be underestimated or degraded.

The journalist's problem is that 95+ % of his readership has never heard of LZ77 or LZW. Thousands of formats use some LZW variant; Lempel cannot be credited for all of them. So, let me dig out a couple that are well known to common man, and attach Lempel's name to those! It doesn't matter if Lempel himself never even heard about those formats (well, he certainly did know both PDF and MP3!); the essential thing is to associate his name with something great!

So why didn't the journalist mention e.g. Microsoft .docx? Probably because the majority of the readership would refuse to believe it. You can make them believe that Lepel could take credit for MP3 or PDF, because they know very little about the development of those formats, so let's go for those rather than .docx!

Many (40+) years ago I read an informal study of major technical innovations, among them the car, telephone, radio and several others, and correlated the information in the major encyclopedias in the US of A, England, France, Germany, Italy (maybe others as well; I don't remember all the details): Which importance did each 'national encyclopedia' give to developers of their own country to the technology? To which degree did they downscale the contribution from persons of other nationalities? When presented side by side, the results could be described as 'hilarious'.

After I read this study, I always have been somewhat skeptical to any source trying to glorify beyond limits any person of its own nationality. Lempel doesn't need that! His work certainly was so great that it can stand on its own, without trying to give him credit for other format that he never touched, as a developer.
