A biography of 19th century British astronomer Norman Robert Pogson and his family has been published recently. Pogson did most of his work in Chennai (or Madras as it was then). His daughter, Elizabeth Isis, worked as his assistant and became the first meteorologist (after her father) in south India. The book titled Astronomer Norman Pogson and his Amazing Family is available on Amazon.
This is not an academic work, but a readable family story, revealing new insights on the life of Pogson, whose many achievements were sadly overlooked in his day. Family papers saved over the years reveal a very different man from the one academic papers show. He mentored the first modern Indian astronomer, Chinthamani Ragoonatha Chary. Variable stars were his passion, and today we still use the Pogson Ratio to measure stellar brightness. The book contains many historical photographs, including several of the old Nungambakkam Observatory.
