Winifred Edgerton Merrill

Winifred loved stars and numbers. Her parents built her a home to watch the sky. She studied math at a big school for men. She was the first American woman to earn a top math degree there. At first, the school said no. She did not give up. She spoke to the leaders one by one. They finally said yes. The students cheered for her for two minutes. She even used math to study a comet. She was a very smart leader.

Winifred Edgerton Merrill was a great math thinker. She was born in Ripon, Wisconsin, in 1862. Her parents built her a small home observatory. This is a place to look at the stars. Winifred loved the sky. She used math to study a comet in 1883.

She went to Columbia University to study math. At that time, the school was only for men. She wanted to earn a PhD, which is the highest degree. The school leaders said no at first. Winifred did not stop. She spoke to the leaders one by one. In 1886, they gave her the degree with high honors. The male students cheered for her for two minutes.

Winifred was the first American woman to get a PhD in math. She also taught math for many years. Later, she started a school for girls. This was the Oaksmere School. She also worked as a librarian in New York City. A portrait of her hangs at Columbia. It says, "She opened the door."

Winifred Edgerton Merrill was a pioneer in the world of math. She loved to look at the stars and study how they moved. Her parents even built a small home observatory for her to use. This allowed her to watch the sky from her own yard. In 1883, she used math to study a comet called Pons-Brooks. She used data from the Harvard observatory to find its path. This showed how math can help us understand space.

Winifred wanted to study at Columbia University. At that time, the school was only for men. She asked to use their telescope to help her studies. In 1884, the leaders said yes to her request. They called her an "exceptional case." They told her not to disturb the male students. She worked as a laboratory assistant to the director. This gave her a way to learn more about astronomy.

Getting her highest degree was a very hard job. Winifred wanted to earn a PhD in mathematics. A PhD is the highest level of learning a person can get. The school leaders rejected her first request for the degree. President Frederick A. P. Barnard told her to talk to the leaders one by one. She followed his advice and spoke to each person. In 1886, the board voted unanimously to give her the degree. She earned it with high honors.

Her success was a huge event for the school. When she received her diploma, the students were very happy. Newspaper reports say the men cheered for her for two full minutes. Winifred was the first woman to get a degree from Columbia. She was also the first American woman to get a PhD in math. Her thesis was very long and used many difficult math ideas. It focused on things like geometry and equations.

Winifred spent her life teaching and learning. She taught math at many different schools. In 1906, she started the Oaksmere School for Girls. She ran that school until 1928. She also found a way to turn signatures into music in 1919. Later, she worked as a librarian in New York City. Today, a portrait of her hangs at Columbia University. It has a special message that says, "She opened the door."

Winifred Edgerton Merrill was a historic figure in American mathematics. She achieved several milestones that changed the path for women in science. She was the first woman to receive a degree from Columbia University. She was also the first American woman to earn a PhD in mathematics. Her life was defined by a deep interest in numbers and the stars. Through her work, she proved that women could master the most complex mathematical theories.

Winifred's interest in science began with astronomy. Her parents, Clara and Emmett Edgerton, provided her with a small home observatory. This allowed her to observe the sky from her own home in Ripon, Wisconsin. In 1883, she used data from the Harvard observatory to study a comet. This comet was known as the Pons-Brooks comet. She used mathematical calculations to determine its specific orbit. This early success showed her talent for using math to explain the universe.

To further her studies, Winifred sought access to Columbia University. At that time, the institution was an all-male school. In February 1884, the board of trustees granted her permission to use their telescope. They labeled her an "exceptional case." They also gave her a specific instruction. They told her not to disturb the male students. Winifred accepted a role as a laboratory assistant to the observatory director. She studied under professors such as John Krom Rees and William Guy Peck.

Winning her doctorate required great persistence. Winifred applied for a PhD in mathematics, but the trustees rejected her first request. President Frederick A. P. Barnard gave her important advice. He suggested she speak to each trustee individually. Winifred followed this plan and met with the leaders one by one. In 1886, the board held a new meeting. They voted unanimously to award her the PhD with high honors. This was a major turning point for women in higher education.

Her doctoral thesis was highly advanced and technical. It was titled "Multiple Integrals and Their Geometrical Interpretation of Cartesian Geometry." The work explored many complex areas. These included trilinears, triplanars, tangentials, and quaternions. She also used determinants, invariants, and covariants to investigate the theory of equations. The granting of her degree was the most important event of the 1886 Columbia Commencement. When she received her diploma, the male students cheered for two full minutes.

Winifred had a long and varied career in education. She taught mathematics at several different institutions. In 1887, she married Frederick Merrill, a fellow Columbia graduate. She declined a professorship at Wellesley College to focus on her new life. Later, in 1906, she founded the Oaksmere School for Girls. She served as the director of this school until 1928. She also served as a trustee for Wellesley College. In 1919, she even created a system to translate signatures into musical notes.

Her legacy remains visible in academic institutions today. A portrait of Winifred hangs in a Columbia University building. The inscription on the portrait reads, "She opened the door." This phrase honors how she broke barriers for others. Her life connected the worlds of mathematics, astronomy, and education. She showed that math is not just about numbers, but about understanding the structure of our world.
