    "abstract": "In a paper appearing in Annalen der Physik in 1930 Leon Rosenfeld invented\nthe first procedure for producing Hamiltonian constraints. He displayed and\ncorrectly distinguished the vanishing Hamiltonian generator of time evolution,\nand the vanishing generator of gauge transformations for general relativity\nwith Dirac electron and electrodynamic field sources. Though he did not do so,\nhad he chosen one of his tetrad fields to be normal to his spacetime foliation,\nhe would have anticipated by almost thirty years the general relativisitic\nHamiltonian first published by Paul Dirac.",
