Nuclear magnetic resonance was formulated in 1946. Who received the 1952 Nobel Prize in Physics for that work?

1. Nuclear magnetic resonance was formulated in 1946 by F. Bloch and E. Purcell. 2. The 1952 Nobel Prize in Physics went to them for that work. 3. Imaging built on the same effect came decades later and was renamed magnetic resonance imaging. 4. P. Lauterbur and P. Mansfield took the 2003 Nobel Prize in Medicine for imaging applications. 5. A. Fert and P. Grunberg took the 2007 physics prize for giant magnetoresistance, a separate discovery. 6. Hall and Oersted worked in the 19th century, long before any of these prizes existed. _Source: OpenStax College Physics (CC BY 4.0), Ch 22 "Magnetism", section 22.11 More Applications of Magnetism_
