In a "Fireside Chat" during the 1992 AERA Annual Meeting, Lee J. Cronbach remarked on his only meeting with Georg Rasch. In 1955, Cronbach was commissioned by the Office of Naval Research to travel to Europe, meet the leading researchers in educational measurement and report back on interesting ideas. While in Copenhagen, Denmark, Cronbach met with Rasch who was then doing bio-assay work for the Serum Institute. Writing enthusiastically with chalk on a blackboard, Rasch started to explain the multiplicative form of his model. But in almost the first sentence he stated that "our scales have an absolute zero". This immediately alienated Cronbach because he had recently been in dispute with Louis Guttman and Jane Loevinger on the existence and nature of natural zeroes. Consequently, when Cronbach submitted his report on his return from Europe, he felt that Rasch's work had so little merit that he did not even give it a note. As a result it was 12 years before Rasch's work came to the notice of the American educational measurement community.
Cronbach's current  opinion is that the Rasch model works well for messy data. He perceives its chief drawback to be its insistence on uni-dimensionality, and its incompatibility with multi-dimensionality.
[These shortcomings are demanded as necessities in all ordinary measurement devices!]
