Arlene Blum (born March 1, 1945) is an American mountaineer, writer, and environmental health scientist. She is best known for leading the first successful American ascent of Annapurna (I), a climb that was also an all-woman ascent. She led the first all-woman ascent of Denali ("Denali Damsels" expedition), and was the first American woman to attempt Mount Everest. She is Executive Director of the Green Science Policy Institute. Early life Blum was born in Davenport, Iowa, and raised from the age of five on in Chicago by her Orthodox Jewish mother and grandparents. In the early 1960s, she attended Reed College in Portland, Oregon. Her first climb was in Washington, where she failed to reach the summit of Mount Adams. However, she persevered, climbing throughout her college days. She was rejected from an Afghanistan expedition in 1969, with its leader writing to her, "One woman and nine men would seem to me to be unpleasant high on the open ice, not only in excretory situations but in the easy masculine companionship which is so vital a part of the joy of an expedition." In 1970, she requested to join a high altitude expedition, but was told that she was welcome to come as far as the base camp to "help with the cooking." However, she was able to go climbing as part of her research for her senior thesis, which was on the topic of volcanic gases on Oregon's Mount Hood. Blum was graduated from Reed in 1966 and attended MIT and UC Berkeley, where she earned a PhD in biophysical chemistry in 1971. After graduate school, Blum embarked on what she called the "endless winter" – spending more than a year climbing peaks all over the world. Major climbs Blum was part of the first all-woman team to ascend Alaska's Denali in 1970. She was deputy leader for the ascent. She participated in a 1976 expedition up Mount Everest as part of the American Bicentennial Everest Expedition, but did not reach the summit. In 1978, she organized a team of eleven women to climb the tenth highest mountain in the world, Annapurna (I) in Nepal which, until then, had been climbed by only eight people (all men). It was called American Women's Himalayan Expeditions – Annapurna. They raised money for the trip in part by selling T-shirts with the slogan "A woman's place is on top". The first summit
