    Marie Curie was actually born as Maria Sklodowska. She was the youngest of five children. Her mother was the headmistress of a school for girls and her dad taught math and physics.

    He was born the son of a Protestant pastor.
  • Period: to

    Wegener's lifetime

  • Marie Curie Graduates from High School

    She was interested in science. She was a very smart student and she graduated from high school with top grades when she was fifteen.

  • Marie Curie goes to study in a school in Paris

    She went to Paris because women could go to college in the school in her country. In Paris, she got to learn from some of the best minds in the era. She signed her name as Marie when she went to the school. She was one of twenty-three women in the school. This was still at the point in time when people thought that women shouldn't study science, but Marie was very dedicated.

  • Marie Curie got a degree in physics

    She passed her exam with the highest marks in her class and was the first woman to get a degree in physics from that school.

  • X- rays waves are discovered

    Scientists all over the world were making lots of scientific discoveries. A German scientists discovered x-ray waves. This would help Marie Curie with her own discoveries later in life.

  • Marie marries Pierre Curie

    Marie was thinking about going back to Poland, but she met Pierre Curie, who was a French scientist, and they got married. They lived in a small apartment and Pierre worked at a college professor.

  • Marie Curie gives birth to Irene

    Marie and Pierre's first daughter, Irene, was born. She also began her work with radioactivity

  • Marie Curie announces the discovery of radium and polonium

    Marie tested lots of different minerals. One of them, which was called pitchblende, was believed to be made up of mostly uranium and oxygen, but Marie found that it gave off much stronger X-rays then they elements usually did. Marie and Pierre worked tirelessly, trying to separate the elements. They discovered radium and polonium and created a term to express how much radiation an element gives off. This term is radioactivity.

  • Marie Curie get the Nobel Prize in physics

    Marie shared the Nobel Prize in physics with her husband, Pierre, and Antoine Henri Becquerel. She was the first woman to receive a Nobel Prize

    He wrote a book with Vladimir Koppen. it was called The Thermodynamics of the Atmosphere,

  • Marie Curie get the Nobel Prize in chemistry

    Marie was determined to figure out where the elements that she had found went in the newly formed periodic table. She found out and got a Noble Prize for it. She was the first person get two Nobel Prizes. She traveled to Sweden to accept the award, bringing her two daughters with her.

  • Wegener marries Else Koppen

  • Marie Curie provided a mobile X-ray for soldiers

  • Marie Curie establishes the Radium Institute

    She did this to promote the research on radioactivity.

  • Wegener publishes another book

    He got more evidence about the continents fitting together and published it in a book called The Origin of Continents and Oceans. He claimed that about 300 million years ago, the continents formed a single mass that he labeled “Pangaea,” a Greek word meaning “whole Earth." He was not the first to express this idea but he was the first to use extensive evidence from different scientific approaches to prove it. He used fossil evidence. He found large-scale geological feature that matched.

It had canyons, trenched and volcanic mountains. He realized that the Earth's crust was moving apart from one another, so he published his theory in a book.
