A forgotten theory of quantum gravity: Suraj N. Gupta and his quantization of general relativity - The European Physical Journal H Gupta was among the first to attempt the quantization of Einstein’s nonlinear theory of gravity. He had an independent program to quantize gravity in a manner akin to electromagnetism, which spanned at least two decades. He adopted the flat-space views of Rosen and Papapetrou and built his theory around these ideas. Although he was well known for his work in quantum electrodynamics, little is known about his work in quantum gravity. For that reason, in this paper, we try to present a historical overview of his research program. https://doi.org/10.1140/epjh/s13129-026-00119-z
