Jack Laundon

Jack Rodney Laundon (28 July 1934 – 31 December 2016) was a British lichenologist and became President of the British Lichen Society.

Education and personal life
Jack Rodney Laundon was born 28 July 1934 in Kettering, Northamptonshire. He was educated at Park Road School, Kettering Central School and Kettering Grammar School, and then worked at the British Museum (Natural History) from 1952 - 1990, mainly in the lichen section. He married Rita June Bransby in 1958 and they had one daughter. He died 31 December 2016.

Career
He was interested in lichen from his teens, and developed his interests in lichen ecology and taxonomy as well as the specimen curation and identification required by his post. This included curating the collection of specimens from Erik Acharius held at the museum. He helped establish the use of chemotaxonomy for lichens at the museum and was active in verifying specimens sent to the museum. His application of the International Code of Botanical Nomenclature was sometimes controversial and led to changes in the code so that species names could be proposed for retention.

He published over 150 articles and several books during his career. These included a popular book Lichens  (1986, 2001) illustrated with his own photographs. In 1956 he published a survey of the lichens of Northamptonshire, and was the first to apply the Scandinavian method of lichen communities to the UK. In 1960 his observation of Lecidea (now Placynthiella) oligotropha in Northamptonshire was published. His surveys of the lichens of London in the late 1960s were the first to map species distributions relative to atmospheric sulphur dioxide levels. His records from gravestones demonstrated that lichen communities were retained on old memorials but did not colonise new ones. He continued to record and publish about lichen distributions until 2012, showing that lichens returned once sulphur dioxide levels fell.

Laundon was a founder member of the British Lichen Society. He was President of the Society in 1984–1985, having been editor of the British Lichen Society Bulletin from 1963 until 1979, and Honorary Secretary from 1964 - 1984. He was elected as Honorary member of the Society in 1988, and received the Ursula Duncan Award in recognition of his services to the British Lichen Society in 2007.

He edited The London Naturalist from 1971 until 1979 and the Bulletin of the British Museum (Natural History), Botany Series from 1977 until 1990. He was a life member of the Museums Association, and was awarded a Fellowship of the Association in 1972.

He was required to retire in 1990 as part of restructuring at the museum as it moved away from taxonomy, but he continued to be very active with lichens and Northamptonshire local history, including authoring several publications, until mid-December 2016, shortly before his death.

Legacy
The lichen Lepraria jackii was named in his honour in 1992, and the lichen products jackinic acid and norjackinic acid were described in 1995 and named after him. Other eponyms include Phoma laundoniae, Camposporium laundonii, and Puccinia laundonii.

Laundon has been credited for introducing the term in a 1995 publication, in an attempt to clarify what he thought were inadequate terms available to describe the range of fungal-algal interactions in the lichen symbiosis.

Trees were planted in his memory by the Kettering and District Natural History Society at Twywell Hills and Dales in November 2019
