Markku Häkkinen is a former sea captain who embarked on a second career as a banana specialist in the 1990s. He became one of the world's leading authorities on the taxonomy of wild bananas in the course of a career than spanned more than 20 years. In the spring of 2014, Markku Häkkinen was diagnosed with amyotrophic lateral sclerosis. The disease forced him to give up field work, but he continued writing articles and corresponding with people from all over the world. He died on 5 December 2015 at the age of 69.
Häkkinen was born in 1946 in Pyhäjärvi, central Finland. After graduating from high school, he enrolled at the Kotka Maritime Research Centre from which he graduated as a sea captain in 19751 . He retired ten years later. In the meantime, he had developed an interest in natural history and botany. During a visit to Thailand, he became intrigued by banana flowers on sale in a market.
As a self-taught botanist with no formal academic training, he initially had difficulties getting published in scientific journals2 . Eventually the rejections stopped coming with the result that between 2001 and 2015 he published more than 80 scientific and popular articles, including accounts of his trips to Borneo, China, Thailand and Vietnam, among other places he explored3 . Over the years, he made 21 expeditions to document the diversity of wild species of bananas in Asia.
Häkkinen described 49 taxa (species, subspecies and varieties of Musa). He also used his knowledge of the taxonomic literature and his familiarity with the international code of nomenclature for algae, fungi and plants4 to clear up some of the confusion surrounding the taxonomy of bananas.
For example, whereas the rules of botanical nomenclature dictate that the first name used to describe a plant has priority over all later names, Häkkinen and his collaborator Henry Väre from the Finnish Museum of Natural History argued to defer to usage in the cases of Musa velutina and Musa balbisiana5 . He also consulted herbarium specimens all over the world and reviewed 442 published names in the process of producing a checklist of Musa names6 . He also collaborated with molecular systematists to take his taxonomic insights to a higher level, that of the sections. In 2013, Häkkinen published a revision that reduced the number of sections from 5 to 27 .
In 2009, the Linnean Society of London gave Häkkinen the HH Bloomer award, the association's highest recognition for a self-taught botanist8 . It is awarded every year to an amateur naturalist who has made an important contribution to biological knowledge. In 2015, he was honoured with a Significant Cultural Act Award from the Finnish Cultural Foundation for his years of work on the taxonomy of wild bananas9 .
He was a visiting researcher at the University of Helsinki’s Natural History Museum and the Chinese Academy of Sciences’ Xishuangbanna Tropical Botanical Garden, as well as a member of MusaNet’s Taxonomic Advisory Group. He was also a member of the International Association for Plant Taxonomy and an Emeritus Member of the Botanical Society of America1 .
