Elizabeth Agassiz, born Boston, Massachusetts.

Elizabeth Agassiz earned her reputation as scientific partner and wife of Louis Agassiz, a well-known naturalist, and as an energetic advocate for women’s education. She married Agassiz in 1850, becoming stepmother to his three children. Elizabeth became a principal organizer in her husband’s scientific expeditions, notably to Brazil (1865-1866), and later to the Straits of Magellan (1871-1872). She continued her own scientific adventures, including co-authoring with her son Alexander Agassiz a treatise on the ‘radiate’ marine fauna of Massachusetts (Elizabeth C. Agassiz and Alexander Agassiz, 1871; the book provided detailed descriptions of included corals, jellyfish, sea anemones (Coelenterates), and Echinoderms, crinoids, holothurians, star fish).

She was elected to the American Philosophical Society in 1869, only the second woman to have gained admission (the first elected woman Princess Dashkova, president of the Imperial Academy of Sciences in St. Petersburg in in 1789).  Louis Agassiz died in 1872.

At a time when wives of their husbands’ scientific publications were usually relegated to the acknowledgements, A Journey in Brazil (Louis Agassiz and Mrs. Louis Agassiz, 1868) represented a partnership that combined Elizabeth’s transcriptions of her husband’s notes, and her own contributions to the science and Brazilian culture; much of the book is written in the first person (Elizabeth). Louis Agassiz is quoted thus in the Preface: “In consequence of this mode of working, our separate contributions have become so closely interwoven that we should hardly know how to disconnect them, and our common journal is therefore published, with the exception of a few unimportant changes, almost as it was originally written.”.

After Louis’ death, Elizabeth’s energies tended to focus on education. In 1874 she co-founded Radcliffe College for women that was annexed to Harvard University. Her dogged persistence saw the College gaining degree-conferring status is 1894; she was President of the College until 1899. Radcliffe became part of a group of women’s colleges referred to as the Seven Sisters.

I can’t reproduce it here (Copyright) but have a read of Jessy Randall’s poem Elizabeth Cabot Agassiz (1822–1907) published in Mathematics for Ladies: Poems on Women in Science by (Goldsmiths Press, 2022).

Soft sediment, and possibly weak-rock deformed turbidites at an iconic outcrop in Lower Miocene Waitemata Basin, Auckland. Deformation was dominated by hydroplastic (folding) but some fold limbs were detached or pulled apart by extension and brittle failure (P). Liquefaction also occurred in some fold hinges – fluid pressures were elevated during folding. The unit is underlain by a relatively non-deformed bed (mostly hidden in this view). The overlying sandy turbidite (T), also non-deformed, infilled hollows and draped detached sand beds that protruded the surface (red arrows).

A classic topographic expression of resistant regressive sandstone cycles, each culminating in a maximum flooding surface in parasequences from the Jurassic Bowser Basin, northern British Columbia. The MFS in the foreground occurs just above the prominent bench where it is overlain by coarsening upward shale-sandstone of the succeeding regression. At least four such packages are present in this view (arrows indicate approximate MFS positions). Maximum regressive surfaces are also present below the MFS, as shown in the previous image. In each cycle, the transgressive package accounts for 10% or less of the total cycle thickness.
