I thought Marcel Grossmann was usually credited with helping Einstein with the tensor approach to General Relativity. All of this was more salient at the time, which the article points out: Hilbert carried a grudge against Einstein for a period of time. Lorentz was bitter about Einstein getting credit for special relativity to the end of his days, and Einstein denied ever having read Lorentz's or Poincare's papers even long after he had moved to the Institute for Advanced Studies. The bitterness and personal politics involved have faded. It is now interesting just from an academic (historical) standpoint.

A lot of quantum field theorist refer to "Einstein summation convention" which is a special case of Ricci calculus and is a notation that was developed together with Levi-Civita by Ricci in their contributions to the field of relativity. At least most quantum field theorist know about Levi-Civita through the Levi-Civita tensor. Given the controversy described in this article one wonders why they are called the Einstein equations and the Hilbert-Einstein action when Einstein indusputably had nothing to do with the derivation of the action principle but Hilbert disputably is responsible for the derivation of the field equations. At the very least people talk about the Lorentz transformation and the Poincare group.

Since general relativity was essentially a unification of the spacetime defined by Maxwell's equations (special relativity) and gravitation, the quest to fully unify the theories that began with Lorentz and Poincare pointing out the strange transformation properties of electric matter continued. A lot of people are aware of Einstein's continued search for a Grand Unified Theory. But in general people are less aware of what theories he introduced (teleparallel gravity for example) or that other people were all trying (Kaluza and Klein for example) and continue to try to this day. In the case of things like dark matter, there might be some hope of measuring the Kaluza-Klein scalar fields or maybe we genuinely need a completely different theory. The history is more interesting because of the missteps, mistakes and politics along the way. It helps us understand the missteps, mistakes and politics of science that are still happening today.

Stigler's law of eponomy says that no scientific law is named after its discoverer [0]. What you're describing is far more common than you might think!

Great, new member in the elite club of rules that make their own exception

I don't think it's the case here: "Stigler himself named the sociologist Robert K. Merton as the discoverer of "Stigler's law" to show that it follows its own decree, though the phenomenon had previously been noted by others.", from the wikipedia article.

I was thinking of this indeed, but felt I was already becoming a bit long winded. ;)
