Reference excerpt

Hannes Hertel is a German lichenologist and taxonomist and was Director of the State Herbarium in Munich, Germany 1992–2004. His specialist areas are the fungi and lichens.

Early life and education Hannes Hertel was born in 1939. His doctorate was awarded in 1967 for work on members of the lichen genus Lecidea that thrive on lime rich rocks and sites. This was undertaken under the guidance of Josef Poelt.

Career He was appointed to an academic post at University of Berlin in 1972 but in 1973 he moved to Munich to take up the post of curator at the State Herbarium in Munich. He became the provisional director from 1985 to 1992 and was then confirmed as Director and remained until his retirement in 2004. His specialist area was the taxonomy of lichens, and especially the genus Lecidea that he had first studied for his doctorate. He and students that he supervised brought order and a critical review of the 1000 accepted and 4000 published names within the genus in the early 1970s. Hannes Hertel was editor of two exsiccata series: Lichenes Alpium et regionum confinium and Lecideaceae exsiccatae. The State Herbarium in Munich contains the lichen collection of Ferdinand Christian Gustav Arnold, 100,000 - 150,000 specimens collected in the nineteenth century. Hertel made a particular effort to transcribe the detailed labels from Arnold's handwriting that was difficult to read and ensured this was published so that the collection could be more easily used by others.

Publications Hertel is the author or co-author of several books and scientific publications. They include:

Honours and awards In 2004 a Festschrift was held on his 65th birthday to celebrate his contributions to lichenology. Hertel was awarded the Acharius Medal for his lifetime's work that has made an outstanding contributions to lichenology in 2008. Several genera have been named after Hertel, including Hertelidea Printzen & Kantvilas (2004), Herteliana P.James (1980); and Hertella Henssen (1985). Many species have also been named to honour Hertel. These include: Biatora hertelii Printzen & Etayo (1998); Caloplaca hanneshertelii S.Y.Kondr. & Kärnefelt (2004); Caloplaca hertelii Søchting, Øvstedal & Sancho (2004); Carbacanthographis hertelii Kalb & Staiger (2004); Carbonea herteliana Hafellner & Matzer (1999); Carbonea hertelii Knoph (1999); Cornutispora herteliana Knoph (2004); Homostegia hertelii D.Hawksw., V.Atienza & M.S.Cole (2004); Lecanora herteliana Calat. & Barreno (2000); Lecidea herteliana Fryday & Coppins (2012); Lecidella herteliana Knoph & Leuckert (1994); Lobaria hertelii Sipman (2004); Placopsis hertelii D.J.Galloway (2004); Porpidia herteliana Gowan (1989); Rinodina herteliana Kaschik (2006); Roccella hertelii Mies & M.Schultz (2004); Sphagnum hertelianum H.Crum (2002); and Trapelia herteliana Fryday (2004).

Worked examples

Example 1 — a first encounter with Hannes Hertel

Start with the simplest possible case. Write down what Hannes Hertel claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hannes Hertel before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hannes Hertel ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hannes Hertel

In research: Hannes Hertel appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hannes Hertel in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hannes Hertel is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1939 births, 20th-century German biologists, 21st-century German scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Hannes Hertel outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
