Asha, did you know there was an astronomical connection with the great poet?
Tennyson named his eldest son Hallam after his friend. Hallam Tennyson - the 2nd Baron - was also the 2nd Governor General of Australia.
Beryl Hallam Augustine Tennyson, a great grandson of the poet, was a writer and BBC radio producer. Although he married, he was gay, which his wife apparently knew. Sadly, in 2005 he was murdered and I think the murder is still unsolved.
But Beryl Hallam's son Jonathan is a Professor of Astronomy at University College London. He has been the head of the Department of Physics and Astronomy, but I don't remember if he is now. Tennyson is quite distinguished in his field and a Fellow of the Royal Society, England's premier scientific society. It's the oldest in the world, dating from the 17th century.
