John Kirk Townsend
John Kirk Townsend (August 10, 1809 – February 6, 1851) was an American naturalist, ornithologist and collector. Townsend was a Quaker born in Philadelphia, the son of Charles Townsend and Priscilla Kirk. He attended Westtown School in West Chester, Pennsylvania and was trained as a physician and pharmacist. He developed an interest in natural history in general and bird collecting in particular. In 1833, he was invited by the botanist Thomas Nuttall to join him on Nathaniel Jarvis Wyeth's second expedition across the Rocky Mountains to the Pacific Ocean. Townsend collected a number of animals new to science. These included birds such as the mountain plover, Vaux's swift, chestnut-collared longspur, black-throated grey warbler, Townsend's warbler and sage thrasher, and a number of mammals such as the Douglas squirrel; several of these were described by Bachman (1839) [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mary Townsend (entomologist)
Mary Townsend (May 14, 1814 – July 8, 1851) was an early American science writer and abolitionist. Born into a prominent Philadelphia Quaker family, she, her parents, and her siblings were educated at the Westtown School. From childhood, Townsend had an interest in insects. She conducted various studies and experiments, examining specimens under a microscope and evaluating their habits. Because illness and the loss of her sight kept her confined to her bed, Townsend taught herself how to write with a braille-like card. In 1844, she published ''Life in the Insect World: or, Conversations upon Insects, between an Aunt and Her Nieces'', which became popular and influential, particularly in influencing other women to pursue science. With her sister Hannah, she also wrote '' The Anti-Slavery Alphabet'', which was published in 1846. Aimed at a juvenile audience, the work taught children the alphabet, using words that would help them develop both a political consciousness and an und ...
