Solomon Schechter was recruited from Great Britain. His religious approach seemed compatible with JTS's, and he assumed the presidency, as well as serving as Professor of Jewish theology. In a series of papers he articulated an ideology for the nascent movement of Conservative Judaism. Many of the Orthodox rabbis associated with JTS vehemently disagreed with him, and left the institution. About 100 days after Schechter's appointment, the Agudath Harabbonim formed, principally in protest, and declared that they would not accept any new ordinations from JTS, though previous recipients were still welcome. The more moderate Orthodox Union (OU), however, still maintained some ties to JTS for decades to come, and some of its rabbis, including Drachman, continued to teach there. In practice, it was often still difficult to tell the difference between many of the less strict Orthodox congregations and the early Conservative synagogues, especially as many of them were once Orthodox-affiliated.
