Maria Ernestine Walsh-Held

Maria Ernestine Walsh-Held (1881–1973) was Swiss botanist and entomologist who lived and worked for many years in Indonesia.

Biography Walsh-Held was born Maria Ernestine Held at Geneva in 1881.

Maria married Herbert Shirley Walsh, an Australian produce merchant and later cattle dealer, Maria and Herbert had two daughters, named Elizabeth Muriel (b. 1907) and Cecile Helene (b. 1908). The Walshes moved to Java in 1911 where Herbert worked as an agent for the cattle firm Jenner and Company.

In 1913 Herbert Walsh was on a trip back to Australia where he died on 20 November 1913 as a result of an accident, after being hit by a train on the Bunbury railway bridge at East Perth.

After the death of Herbert, Maria did not remarry. Maria Walsh-Held spent about four decades working in Indonesia before repatriating to Switzerland. Walsh-Held died at Geneva in 1973. By 1915 Walsh-Held had begun scientific collecting in earnest to support herself financially. Around this time Walsh-Held was in correspondence with the Lepidopterist Margaret Fountaine (who had spent a period in Soekaboemi) about Papilio butterflies.

In Timor in the late 1920s Walsh-Held collected the Holotype material of the butterfly Delias lemoulti Talbot, 1931, which she sent to the entomologist and dealer Eugène Le Moult. George Talbot of the British Museum named the new species for Le Moult at Le Moult's insistence, not realising he was not crediting the original collector, and Talbot later expressed his regrets about what had happened:The butterfly was actually discovered by Mrs. Walsh, a resident of Java, who sent her Timor collections to Le Moult. The author was unaware of this at the time and regrets that the species was not dedicated rightfully to the discoverer. The practice among certain dealers, of keeping secret the names and activities of their collectors is unfortunate, and is liable to recoil upon the business. - George Talbot In 1937 Walsh-Held collected plants in north east Borneo accompanied by Aët, a botanist who worked at the Herbarium Bogoriense in Buitenzorg [ Bogor].
