VoronovM.N., a 22-year old astronomer who worked at the Tashkent Observatory, claimed in 1935 to have extended Leveau's theory for computing the perturbations of the minor planets from the 2nd to the 3rd order, and that with an amazing computing speed. Astronomische Nachrichten published his results, and he joined the staff of Pulkovo Observatory. A year later, his work proved to be fraudulent.
