Comment: His Google scholar profile https://scholar.google.com/citations?user=xSlT2vsAAAAJ shows a clear pass of #C1 and I think the two articles about him linked from this one http://dkrause.cfh.ufsc.br/pg/PerfilNewton.htm http://www.unicamp.br/unicamp/unicamp_hoje/ju/junho2003/ju215pg11.html provide enough reliable and in-depth coverage about him to form the basis of an encyclopedia article
