Dr. Marie Maynard Daly was the first African American woman chemist to receive a PhD in chemistry. In addition, she was part of a research team that was working on the precursors to DNA . Marie was born Marie Maynard Daly on April 16, 1921, to Ivan C. Daly and Helen Page, the first of three children. Her father, who had emigrated from the West Indies, received a scholarship from Cornell University to study chemistry; however, he had to drop out because he could not pay his room and board, and he became a postal worker. Daly’s interest in science came from her father’s encouragement and the desire to live his dream.” He later encouraged his daughter to pursue his dream, even though she was a woman and had brothers who were twins. In the 1920s, as a result of the women’s suffrage movement, some women began to aspire to achievement in areas outside the domestic sphere. Marie’s mother encouraged reading and spent many hours reading to her and her brothers. Marie’s maternal grandfather had an extensive library, including books about scientists, such as The Microbe Hunters by Paul De Kruff; she read that book and many others like it. Growing up in Queens, one of the boroughs of New York City, she attended the local public school, where she excelled. She was able to attend Hunter College High School, an all girls’ school affiliated with Hunter College for women. Since this was a laboratory school for Hunter College, the faculty encouraged the girls to excel in their studies. Since Marie had an aptitude for science, the teachers there encouraged her to study college-level chemistry while still in high school. One of the many advantages of living in New York City during that time was that students who had good grades could enter one of the tuition-free colleges run by the City of New York. As a result, Daly enrolled in Queens College, then one of the newest institutions in the City College system, in Flushing, New York.

High school cosmetology students study the methods and effects of various human hair treatments, including permanents, straightening, conditioning, coloring and cutting. Although they are provided with textbook examples of overtreatment and numerous hair disorders and diseases, a view of an individual hair at the high resolution offered by an SEM provides convincing evidence of the hair‘s altered structure. Magnifications up to 2000X provide dramatic differences in perspective. A good quality classroom optical microscope can be very informative at lower resolutions.Students in a cosmetology class are initially split into two groups. One group is taught basic controls on the SEM (focus, magnification, brightness, contrast, specimen X, Y, and Z axis movements). A healthy, untreated piece of hair is initially examined on the SEM The second group cements a piece of their own hair on a stub. The samples are dryed quickly using heat or vacuum while the groups trade places and activities.

The development of a scanning electron microscope (SEM) suitable for instructional purposes has created a large number of outreach opportunities for the Materials Science and Engineering (MSE) Department at Iowa State University. Several collaborative efforts are presently underway with local schools and the Department of Curriculum and Instruction (C&I) at ISU to bring SEM technology into the classroom in a near live-time, interactive manner. The SEM laboratory is shown in Figure 1.Interactions between the laboratory and the classroom use inexpensive digital cameras and shareware called CU-SeeMe, Figure 2. Developed by Cornell University and available over the internet, CUSeeMe provides inexpensive video conferencing capabilities. The software allows video and audio signals from Quikcam™ cameras to be sent and received between computers. A reflector site has been established in the MSE department that allows eight different computers to be interconnected simultaneously. This arrangement allows us to demonstrate SEM principles in the classroom. An Apple Macintosh has been configured to allow the SEM image to be seen using CU-SeeMe.
