Palynologist as artist. Artist as palynologist.

Gunnar Erdtman, a Swedish botanist, is usually credited for bringing the technique of pollen analysis (often referred to as palynology) to the world (Fægri 1973, Nilsson & Praglowski 1978,Traverse 2007).  Influenced by a now famous 1916 lecture on pollen analysis given by Lennart von Post, Erdtman’s 1921 thesis was the first major palynology publication in a broadly accessible language (Fægri 1973).  He traveled widely, promoting palynology as a tool to study past vegetation and climate, and developed laboratory techniques still used in studies of pollen morphology today (e.g., acetolysis). Furthermore, he published over 200 papers and several books that established the foundation of the science. But this post is not really about Erdtman’s scientific contributions; it is a simple celebration of what Fægri (1973) referred to as his “artist’s perception of forms.”

“Erdtman was a keen observer and had a capacity for imaginatively demonstrating his findings with the talent of an artist […] and the pedagogical skill of a teacher.” – Nilsson & Praglowski 1978

Gunnar Erdtman’s artistic gifts and observation skills were likely inherited, inspired, and cultivated by his family. His father, Elias Erdtman, was a well known landscape painter that studied in France at the height of French Impressionism, and there were artists on his mother’s side as well.  He grew up broadly interested in both art and music.

When he wasn’t using his artistic talents to observe, describe, and document the morphology of pollen grains he apparently enjoyed entertaining his friends with his flute playing, and creating surrealistic drawings (Nilsson & Praglowski 1978), like the “self-portrait” below.

According to Traverse (2007), this is Gunnar Erdtman's "self-portrait as a wood gnome."  From the back of Erdtman's 1954 book, "An introduction to pollen analysis."

Pollen grains are strikingly intricate and beautiful, and Erdtman’s passion for art may have contributed to his interest in palynology.  However, his power as an artist also clearly benefited him as a scientist.  Although almost anyone can learn to identify the general morphological types of pollen, skilled observations are needed to discern the finer structural details of pollen-grain walls and the subtleties of surface texture that enable greater taxonomic precision.  Erdtman was keenly observant of these details.  His observations and meticulously detailed drawings laid the foundation for pollen analysis and established much of the terminology that is still used today to describe pollen features.  I recently looked through Erdtman’s 1954 textbook on pollen analysis, and was struck by the detail and beauty captured in his drawings (shown below).

Selected drawings of pollen and spores from Erdtman’s 1954 text, “Introduction to pollen analysis.”  Insets adjacent to some pollen grains show a magnified view of the surface texture.  Images collected here come from many different, carefully labelled figures (plates).

Art informs science by focusing the scientist’s observation skills.  Science informs art by providing endless source material for the artist.  And both can inspire each other.

Finally, I can’t resist adding this humorous anecdote:

“Professor Erdtman’s devotion to palynology was unmistakable and expressed itself in many different ways. On napkin holders in various hotels he introduced himself and his wife as “I. M. Pollen” (I am pollen) and “U. R. Pollina” (you are pollina) respectively. As a consequence it was only natural to imagine and discuss during the meal, which pollen types were represented in the mixed salad being served. Thus, a good palynologist should never lose an opportunity to test his or her knowledge in the beloved science of palynology.” – Nilsson et al. (1993)
