Eliza Maria Gordon-Cumming

Lady Eliza Maria Gordon-Cumming (1795- 21 April 1842) was a Scottish aristocrat, horticulturalist, palaeontologist and scientific illustrator. Lady Cumming collected and studied Devonian fish fossils from the Old Red Sandstone of Morayshire, Scotland. She amassed a large and well-known collection which she illustrated, along with her daughter Lady Anne Seymour. Lady Cumming worked with other palaeontologists and geologists of the time including Louis Agassiz, William Buckland and Roderick Murchison.
Biography.
Early life.
Lady Cumming was born Eliza Maria Campbell in 1795 in Inveraray to Lady Charlotte Campbell (later Lady Charlotte Bury) and Colonel John Campbell. Her mother was a diarist and novelist and father a soldier and politician.
Palaeontological research.
Lady Cumming was a skilled painter and keen horticulturalist who took up the study of the fossils on her Altyre estate near the Moray Firth around 1839. She collected fossils and instructed workers in the quarries on the estate to bring her any they found. She collected a large number of specimens of fossil fish from the Devonian period and began a correspondence with the most famous geologists of the time; Louis Agassiz, William Buckland and Roderick Murchison all visited her collection in Scotland. She sent illustrations, letters and specimens around Europe, and intended to publish her illustrations and theories on how these fish would have appeared in life. Some of these illustrations survive in the archives of the Geological Society. Some of her ideas about how the fossil remains should be interpreted were later discredited as more fossil evidence came to light, but her illustrations were highly respected. Her work was praised by Hugh Miller, and
...collected these remains and distributed them amongst geologists with the greatest liberality. Lady Cumming had studied the remains with great care, and prepared a series of drawings of all the most perfect specimens with a precision of detail and artistic talent, which few naturalists can hope to attain"
After his visit to Altyre, Agassiz named a species "Cheirolepis cummingae" (also sometimes spelled "cummingii") in honour of Cumming. This species name was later discovered to be a synonym of "Cheirolepis trialli." Many of the fossils in Cumming's collection were personally identified by Agassiz, and the collection is now held by the National Museum of Scotland, the Natural History Museum, London, and the University of Neuchatel.
Marriage and children.
Lady Cumming married Sir William Gordon Gordon-Cumming of Altyre, 2nd Baronet in 1815. They had 13 children including 
Death.
During her 13th pregnancy Cumming was impatient to get back to her studies, writing to Roderick Murchison "I am breathless to be at work again." However, she died on 21 April 1842 due to complications following the birth.
