Ludwig Schaerer
Ludwig Emanuel Schaerer (11 June 1785 – 3 February 1853) was a Swiss pastor and lichenologist. Interested in natural history from a young age, Schaerer trained as a teacher and studied theology in Bern. During his career as a teacher, orphanage director, and pastor, he researched extensively and maintained correspondence with foreign botanists interested in cryptogams. Schaerer was best known for his multi-volume work ''Lichenum Helveticorum Spicilegium'' ("Anthology of Swiss Lichens"), published in 12 parts from 1823 to 1842. This series catalogued and described the lichens of Switzerland, particularly those in the Alps, where he often went on collecting excursions. In another series, he compiled and distributed dried herbarium specimens acquired from his collections. Several lichen taxa have been named in honour of Schaerer. Early life and education Ludwig Schaerer was born on June 11, 1785, in Bern. His father, Johann Rudolf, was a professor of biblical studies and Heb ...

Flora
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ...

Carl Ludwig Willdenow
Carl Ludwig Willdenow (22 August 1765 – 10 July 1812) was a German botanist, pharmacist, and plant taxonomist. He is considered one of the founders of phytogeography, the study of the geographic distribution of plants. Willdenow was also a mentor of Alexander von Humboldt, one of the earliest and best known phytogeographers. He also influenced Christian Konrad Sprengel, who pioneered the study of plant pollination and floral biology. Biography Willdenow was born in Berlin and studied medicine and botany at the University of Halle. After studying pharmaceutics at Wieglieb College, Langensalza and in medicine at Halle, he returned to Berlin to work at his father's pharmacy located in the Unter den Linden. His early interest in botany was kindled by his uncle J. G. Gleditsch and he started a herbarium collection in his teenage years. In 1794 he became a member of the Berlin Academy of Sciences. He was a director of the Botanical garden of Berlin from 1801 until his death. ...

In 1816 he succeeded Ludolph Christian Treviranus (1779–1864) as professor of natural history at the University of Rostock, where he remained for the rest of his life. He specialized in the field of lichenology, being known for his investigations of the genus ''Cladonia''. During his career, he was highly critical of Swedish botanist Erik Acharius's work; e.g. ''Kritische Anmerkungen zu den Becherflechten in der Lichenographia universalis des Herrn Doctors und Ritters Erik Acharius'' (1810) - (Critical comments on the cup lichen in ''Lichenographia universalis'' of Erik Acharius).

Evangelicalism
Evangelicalism (), also called evangelical Christianity or evangelical Protestantism, is a worldwide interdenominational movement within Protestant Christianity that affirms the centrality of being " born again", in which an individual experiences personal conversion; the authority of the Bible as God's revelation to humanity (biblical inerrancy); and spreading the Christian message. The word ''evangelical'' comes from the Greek (''euangelion'') word for " good news". Its origins are usually traced to 1738, with various theological streams contributing to its foundation, including Pietism and Radical Pietism, Puritanism, Quakerism, Presbyterianism and Moravianism (in particular its bishop Nicolaus Zinzendorf and his community at Herrnhut).Brian Stiller, ''Evangelicals Around the World: A Global Handbook for the 21st Century'', Thomas Nelson, USA, 2015, pp. 28, 90. Preeminently, John Wesley and other early Methodists were at the root of sparking this new movement during the ...
