No Pink (Margaret Crane)

Henrietta Vansittart, née Lowe (1840-1883) was a British engineer. After the death of her father, she developed his propeller design to patent maturity. Without attending formal school or university, she achieved what her father had previously failed to do: she was awarded a US patent (1868) and numerous other patents for the invention, which saved fuel and thus made shipping more efficient at the time. The technique of this workThe artist mixes oil paint with ink, which forms the basis of this depiction in an experimental process. First, a fine preliminary drawing is made on the canvas with light, thinly applied oil paint. (Some of these contours can be seen below right.) After the underpainting has dried, the canvas is randomly colored with water and ink. This creates surfaces and areas that are not wetted by the ink. In the final step, the artist fills in all the remaining areas with oil paint. About the portrait There is only one documented depiction of Henrietta Vansittart that actually shows her: On a newspaper page, you can see her holding a greatly reduced model of her ship's propeller. The original image is black and white. The artist imagines a color scheme for the engineer's clothing and hair color.

Inge Lehmann (1888-1993) was a Danish geophysicist and the first dedicated seismologist. She observed deviant waves after a major earthquake in New Zealand in 1929 and then proved in 1936 that the earth must have a hard core - and not, as previously assumed, a liquid magma core. Inge Lehmann researched and published throughout her life, most recently in 1987, when she was almost 90 years old. In an interview, she once soberly stated: "You should know how many incompetent men I had to compete with in vain." The painting technique of this work The basis is a white canvas, which initially was colored with ink in a random process. In the next step, the artist paints the portrait on these colored areas. The idea behind this type of representation is the fact that women and their contributions are not seen clearly and unambiguously. The portrait series aims to make women and their achievements - like Inge Lehmann - more visible and thus better known. About the portrait This portrait is based on a historical photo of Inge Lehmann from the 1930s - the very time in which she made and proved her most important groundbreaking discovery. The choice of green as the color for her jacket is an artistic interpretation. Who was Inge Lehmann? Lehmann, who had studied mathematics at the Universities of Copenhagen and Cambridge, investigated how the energy released by earthquakes moves through the earth. While examining data from a major earthquake in New Zealand in 1929, she discovered that energy waves in the earth's layers, known as seismic waves, occurred in unexpected places.She suspected that they must have been deflected by some kind of boundary in the earth's core.This led her to theorize in 1936 that the Earth's core consists of two parts: a solid metal core surrounded by an outer liquid core, disproving the common theory of a completely liquid core.Despite her success, Lehmann recounted how she struggled against the male-dominated research community, once remarking: "You should know how many incompetent men I had to compete with in vain." In addition to numerous awards and honors for her scientific achievements, a beetle species Globicornis (Hadrotoma) ingelehmannae was named after her in 2015.

Trota de Salerno (~1090-1160) was a physician and gynecologist from Salerno (Italy), where a large community practiced medicine in the 11th century. Trota de Salerno summarized the knowledge about the female body and the treatment of female ailments in a large collection of writings, later known as the "Trotula". This book was the standard work on gynecology for centuries and was distributed throughout Europe. A monk once changed her name to "Trotulus", as he probably thought a female name was a mistake. Later, in the 19th century, a historian wanted to know Trota not as a doctor but as a midwife. The fact that women and their abilities were considered untrustworthy and that they "should actually be men" is not uncommon in historiography, which has been dominated by men right up to the present day. The painting technique of this workThe basis is a white canvas, which was colored with ink in a random process. In the next step, the artist paints the portrait on these colored areas. The idea behind this type of representation is the fact that women and their contributions are not seen clearly and unambiguously. The portrait series aims to make women and their achievements - like Inge Lehmann - more visible and thus better known. About the portrait This portrait is based on the image of Trota de Salerno in a manuscript from the 12th century.It is therefore not a portrait in the usual sense - there are no sources about Trota's appearance. The word "Trotulus" is crossed out on the picture, below which is written: Trota de Salerno - in a medieval calligraphy. Who was Trota de Salerno? Trota de Salerno (also known as Trocta) was a doctor and medical writer in the southern Italian coastal town of Salerno who lived in the first or middle decades of the 12th century. She propagated cleanliness, a balanced diet, exercise and the avoidance of stress - a very modern combination. Her book "De curis mulierum" on women's illnesses was very progressive for the time.Her fame spread as far as France and England in the 12th and 13th centuries.After that, apart from a distorted image of her work that survived in the Trotula treatises, her work fell into oblivion until it was rediscovered in the late 20th century.How did Trota come to write down these texts? The literacy of women in southern Italy at this time is not well documented, which raises the question of why the "De curis mulierum" was written down at all.One scholar, Dr. Monica Green (Professor of Modern Early History, Arizona State University), now suspects that "De curis mulierum" may not have been written down for the benefit of women in Salerno, but for an audience in England who wanted general information about medical practices in distant Salerno. Both England and southern Italy were under Norman rule at this time, and the transfer of southern Italian medical writings to Normandy and especially to England is well documented for this period. The manuscript in which we find the earliest copy of the original version of De curis mulierum (from the early 13th century) appears to have been written in both Italy and England.
