Bengal produced a number of high rank scientists, but ignored their history. One such unsung hero is Upendra Nath Brahmachari (1873–1946). Brahmachari discovered pentavalent antimonials, Urea Stibamine for the treatment of kala-azar in 1922 long before the discovery of penicillin. In the history of chemotherapy his contribution stands as major landmark. The drug effectively countered the epidemic of kala-azar during the late twentieth century in the vast track of the Gangetic plain and the Brahmaputra valley. The discovery testifies the monument of labor, knowledge and amply rewarded the clinical success it had attained. He was nominated for the Fellowship of the Royal Society of London, as well as Nobel Prize. The present communication1 gives a short review about his life and scientific work.

联合国Brahmachari：诺贝尔奖和伦敦皇家学会奖学金的科学成就和提名

孟加拉产生了许多高级科学家，但忽略了他们的历史。这样的无名英雄就是Upendra Nath Brahmachari（1873–1946）。Brahmachari在发现青霉素之前就于1922年发现了五价锑素Urea Stibamine，用于治疗黑热病。在化学疗法的历史上，他的贡献是重要的里程碑。该药物有效地抵抗了二十世纪后期在恒河平原和雅鲁藏布江谷的广阔轨道上发生的黑热病。该发现证明了劳动，知识的丰碑，并充分奖励了其取得的临床成功。他获得伦敦皇家学会奖学金和诺贝尔奖提名。本来文1对他的生活和科学工作作了简短回顾。
