generally; to Hoyle's having described its key equation only in words rather than writing it prominently in his paper; and to Hoyle's incomplete review of the B2FH draft. Writing of the paper The Caltech nuclear physicist William Alfred Fowler used his sabbatical leave to visit Hoyle in Cambridge from 1954 to 1955. The pair invited Margaret Burbidge and Geoffrey Burbidge to join them in Cambridge, as the couple had recently published extensive work on stellar abundances that would be required to test Hoyle's hypothesis. The quartet collaborated on several projects whilst in Cambridge; Fowler and Hoyle began work on a review that would become B2FH. Fowler returned to Caltech with the work far from complete, and encouraged the Burbidges to join him in California. Both of the Burbidges had temporary positions created for them in 1956 at Caltech by Fowler for this purpose. The first complete draft was completed by the Burbidges in 1956 at Caltech, after adding extensive astronomical observations and experimental data to support the theory. Margaret Burbidge, the paper's first author, completed much of the work whilst pregnant. The final paper is 104 pages long, with 34 plots, 4 photographic plates, and 22 tables; despite this length, it does not have an abstract. Some have presumed that Fowler was the leader of the group because the writing and submission for publication were done at Caltech in 1956, but Geoffrey Burbidge has stated that this is a misconception. Fowler, though an accomplished nuclear physicist, was still learning Hoyle's theory in 1955 and later stated that Hoyle was the intellectual leader. The Burbidges also learnt Hoyle's theory during 1954–55 in Cambridge. "There was no leader in the group," G. Burbidge wrote in 2008, "we all made substantial contributions". Recognition B2FH drew scientific attention to the field of nuclear astrophysics. By reviewing the theory of stellar nucleosynthesis and supporting it with observational evidence, B2FH firmly established the theory among astronomers. Fowler was awarded half of the 1983 Nobel Prize in Physics, which has sometimes been erroneously stated was for his contributions to B2FH. The Nobel committee stated that the prize was for Fowler's decades of experimental work on the rates of thermonuclear reactions in stellar cores. Fowler's contributions to B2FH included the nuclear physics of the s-process and the r-process. Some have argued that Fred Hoyle deserved similar recognition for theoretical work on the topic, and contend that his unorthodox
