Ha érdekel a sumerológia kutatás- és tudománytörténete pl. az alább írást olvasd el. Ebben szó esik arról is, hogy bár Halevy nézete egy időben és bizonyos körökben mértékadónak számított, de korántsem mondható el, hogy "uralkodó" lett volna.

"In some notes added to Zimmern's first book Delitzsch took occasion to speak in warm terms of Halevy's very important contributions to the subject, and while not yet ranging himself at his side, declared that his view deserved very close examination. Well might the great French orientalist rejoice over such a promised accession. When the first part of Delitzsch's Assyrian dictionary appeared every page contained proof that in his case Halevy's long and courageous fight had won. Delitzsch had joined the still slender ranks [!!!] of the anti-Accadians, and when his Assyrian grammar appeared a whole paragraph was devoted to a most incisive attack upon the Sumerian theory. The accession ofDelitzsch is the high-water mark of Halevy's theory. The morrow would bring a great change.
Delitzsch's grammar was received with enthusiasm, as it well deserved to be, but the anti-Sumerian paragraph was severely handled by its critics. In like manner the anti-Sumerian position of the dictionary met with a criticism which indicated that even the great name of Delitzsch was not sufficient to increase confidence in Halevy's cause. Sayce, in a review no less remarkable for the range of its learning than for its scientific spirit, protested against Delitzsch's method. Lehmann, in a big book devoted to the inscriptions of a late Assyrian king devoted an entire chapter to the Sumerian question. In it the whole subject was treated with a freshness and an ability that left little to be desired. Though some minor criticism was passed upon it, none but Halevy dared deny that it marked a step forward in the process of tearing down his elaborate theories.
...
In the very same year in which Delitzsch's grammar appeared Bezold made a brilliant discovery in finding upon an Assyrian tablet the Sumerian language mentioned. In his announcement of this new fact Bezold writes banteringly, asking Halevy to permit the language to live, as the Assyrians had mentioned it by name. Beneath this humorous phrase there lies, however, a quiet note of recognition that the mention was important, though not conclusive as to the main question.
Almost every month after the year 1892 brought some new material to be considered and related to the ever-debated question. The newer discoveries of DeSarzec, the wonderful results of the American expedition to Nippur, the editing of texts found by previous explorers - all these had some link with the Sumerian question. In 1897 Professor Delitzsch, borne down by the weight of fresh evidence, abandoned Halevy's side and once more allied himself to the Sumeriologists."
