Florence Bascom was one of the first women in the US to earn a Ph. D and was the first from Johns Hopkins University. She is known in Geological circles as the first woman Geologist and was the first hired by the U.S. Geological Survey back in 1896. By 1906, as one of the country's leading Geologists, Florence was recognized by her peers as a four-starred geologist in the first edition of American Men of Science.
I don't know about you, but the way I read Dr. Florence Bascom's resigned and mildly contemptuous expression, she is saying "If we have to do this damn photograph let's get on with it so that I can get out of this uncomfortable frock and get back to work!"

Elephants can tell difference between human languages
Study shows they differentiate male, female voices
Wild elephants can distinguish between human languages, and they can tell whether a voice comes from a man, woman or boy, a new study says.
That’s what researchers found when they played recordings of people for elephants in Kenya. Scientists say this is an advanced thinking skill that other animals haven’t shown. It lets elephants figure out who is a threat and who isn’t.
The result shows that while humans are studying elephants, the clever animals are also studying people and drawing on their famed powers of memory, said study author Karen McComb.
“Basically they have developed this very rich knowledge of the humans that they share their habitat with,” said McComb, a professor of animal behaviour and cognition at the University of Sussex in England.
“Memory is key. They must build up that knowledge somehow.”
The study was released Monday in the Proceedings of the National Academy of Sciences.
McComb and colleagues went to Amboseli National Park in Kenya, where hundreds of wild elephants live among humans, sometimes coming into conflict over scarce water. The scientists used voice recordings of Maasai men, who on occasion kill elephants in confrontations over grazing for cattle, and Kamba men, who are less of a threat to the elephants. The recordings contained the same phrase in two different languages: “Look over there. A group of elephants is coming.”
By about a two-to-one margin, the elephants reacted defensively — retreating and gathering in a bunch — more to the Maasai language recording because it was associated with the more threatening human tribe, said study co-author Graeme Shannon of Colorado State University.
“They are making such a fine-level discrimination using human language skills,” Shannon said. “They’re able to acquire quite detailed knowledge. The only way of doing this is with an exceptionally large brain.”
They repeated the experiment with recordings of Maasai men and women. Since women hardly ever spear elephants, the animals reacted less to the women’s and boys’ voices.
In yet another experiment McComb and Shannon altered female and male voices, making female voices sound male by lowering their tone and resonance, and males sound female by raising their pitches. But the clever elephants weren’t tricked, McComb said. They still moved away from the altered male voices and not the altered female voices.
