Käthe Hoffmann facts for kids

Johanna Emilie Katharina Elizabeth "Käthe" Hoffmann (born August 1, 1883 – died December 30, 1960) was an amazing German botanist. A botanist is a scientist who studies plants! She discovered and described many new plant species, especially in places like New Guinea and South East Asia. One plant she helped describe is called Annesijoa novoguineensis.

Käthe Hoffmann was also a high school teacher in Breslau, which is now Wrocław, Poland. Her work was very important for understanding plants. She helped write about 354 different land plant species. This made her one of the top female scientists in the world for describing plants. As of May 2026, the Plants of the World Online website lists 439 plant groups and species that include her name as an expert. This shows how much she contributed to the world of plants!

Who Was Käthe Hoffmann?

Early Life and Discoveries

Käthe Hoffmann was born on August 1, 1883, in a city called Breslau. Today, this city is known as Wrocław and is in Poland. She spent her life dedicated to studying plants.

For a while, some people thought she passed away in 1931. However, this wasn't correct! We know this because she wrote two scientific papers that were published in 1942. One of these papers was even a tribute to another botanist, Ferdinand Albin Pax, who had passed away. Records from Berlin, Germany, and a notice in a botanical journal confirm that Käthe Hoffmann actually died in Berlin on December 30, 1960.

A Mix-Up of Names: Käthe Hoffmann and Käthe Rosenthal

There was another female botanist named Käthe Rosenthal who also worked at the University of Breslau around the same time. Because their names were similar and they worked in the same field, some people sometimes confused them.

Both Käthe Hoffmann and Käthe Rosenthal contributed to a very large and important book about plants called Das Pflanzenreich (which means The Plant Kingdom). In this book, Käthe Hoffmann worked with Ferdinand Pax on sections about a plant family called Euphorbiaceae. Käthe Rosenthal wrote a section about a different plant family, Daphniphyllaceae.

Käthe Rosenthal even wrote a special paper for her PhD in 1916. In her paper, she thanked "Frl. Käthe Hoffmann" for "valuable advice" on her work. This clearly shows that they were two different people! Käthe Rosenthal was born in 1893, which was 10 years after Käthe Hoffmann. So, while they shared a similar name and a passion for plants, they were distinct scientists.

Exploring the Plant Kingdom: Her Major Works

Käthe Hoffmann spent many years working on a huge project called Das Pflanzenreich (The Plant Kingdom). This was a massive collection of books that described all the known plants in the world. Between 1911 and 1924, she and Ferdinand Pax wrote almost all the sections about the Euphorbiaceae plant family for this important work.

At first, her name appeared as "with the participation of Käthe Hoffmann." But as her contributions grew, she was later credited as the second author. This shows how much her expertise was valued and recognized over time. Her work helped scientists around the world understand many different plant species.

• F. Pax with the participation of Käthe Hoffmann (1911). "IV. 147. III Euphorbiaceae–Cluytieae". Heft (issue) 47.
• F. Pax & Käthe Hoffman (1919). "IV. 147. IX Euphorbiaceae-Acalypheae-Plukenetiinae". Heft 68.
• F. Pax & Käthe Hoffman (1924). "IV. 147. XVI Euphorbiaceae-Crotonoideae-Acalypheae-Acalyphinae". Heft 85.

What is an Author Abbreviation?

When botanists describe new plant species, they often add a special short name, called an "author abbreviation," after the plant's scientific name. This tells everyone who first described that plant. For Käthe Hoffmann, her official author abbreviation is

This helps other scientists easily identify her contributions to botany.
