Maxine Singer visits Carnegie's former Department of Plant Biology

Carnegie Science's First Female President

During her fourteen years as President of Carnegie Science, Maxine Frank Singer led the institution into a new era of discovery and impact. As the first woman in the role, she oversaw the construction of the Magellan telescopes at the Las Campanas Observatory in Chile, which have fueled groundbreaking astrophysics research for over 20 years. She also established Carnegie’s first new research department in over 80 years—the Department of Global Ecology—leading the way in studying large-scale environmental challenges.

Singer prioritized education and outreach, creating programs such as the Capital Science Evening lecture series and the Carnegie Academy for Science Education. Her vision and leadership not only strengthened Carnegie Science’s research capacities but also expanded its role as a vital institution for both scientific discovery and education.

Leading the Way in Genetic Research

After earning her Ph.D. from Yale, Maxine Singer joined the National Institutes of Health (NIH) in 1956—a mere three years after the discovery of the DNA double helix.

Her early research, which focused on RNA and DNA synthesis, helped lay the foundation for the decoding of the genetic code in the 1960s. One of her most significant scientific contributions was the discovery of the LINE-1 DNA sequence, which can "jump" within the human genome, causing mutations that may lead to genetic diseases. This breakthrough reshaped our understanding of genetic mobility and its role in evolution and disease. Singer’s scientific work contributed to the development of molecular biology as we know it today, and her legacy continues to influence generations of researchers.

Advocacy for Ethics in Genetics

Maxine Singer was a key figure in creating ethical guidelines for genetic research during a time when public concern was growing. In the early 1970s, as recombinant DNA research and gene splicing gained public attention, Singer became a trusted voice for balancing scientific progress with public safety. Seeing the potential risks of unregulated genetic research, she urged caution in a co-authored letter in Science which ultimately led to 1975 Asilomar Conference. As an organizer of this historic gathering, Singer helped guide discussions among the 150 scientists in attendance, leading to the adoption of voluntary guidelines and safeguards for high-risk experiments. 

Beyond the lab, she was a dedicated advocate for responsible genetic research. Singer engaged with the public at forums, debated critics, and testified before Congress (pictured), helping to build trust and set lasting standards for scientific responsibility. This experience also strengthened her commitment to science education, which she saw as essential for an informed and engaged society.

Science to the People

Throughout her career, Maxine Singer was a dedicated advocate for women and minorities in science. As President of Carnegie Science, she launched several educational outreach initiatives aimed at providing hands-on science experiences to students and teachers in Washington, D.C. Notably, she founded the First Light Saturday science school and the Carnegie Academy for Science Education (CASE), which have served thousands of D.C. students and teachers. 

Singer continued to work with CASE and other programs, such as Math for America, long after her retirement. Her advocacy work has left a lasting impact on STEM education and inspired future generations of scientists, educators, and policymakers.

In Her Own Words

I’ve lived through an extraordinary time in biology, and I’ve been a part of it, and there hasn’t been a day when I’ve wanted to do anything else.

Today, in the United States, the threat which results from the scientific ignorance of policy-makers must be faced. Genetic engineering is only one area of science in which this ignorance can lead to disastrous results. Education can end this ignorance.

The United States is the leader not because we are smarter or richer than other nations but because we are a freer people. Freedom breeds the optimism that is the most fertile ground for science and for innovation.

Any urge to run for cover was suppressed by the sheer pleasure of doing science, by the satisfying—if not always happy—struggle to establish a new fact, by the failures and successes in one after another addicting opportunity to test whether "I can do it."
