Bohr returned to Denmark in July 1912 for his wedding, and travelled around England and Scotland on his honeymoon. On his return, he became a "privatdocent" at the University of Copenhagen, giving lectures on thermodynamics. Martin Knudsen put Bohr's name forward for a "docent", which was approved in July 1913, and Bohr then began teaching medical students. His three papers, which later became famous as "the trilogy", were published in "Philosophical Magazine" in July, September and November of that year. He adapted Rutherford's nuclear structure to Max Planck's quantum theory and so created his Bohr model of the atom.
