    • The Making of a Scientist Richard Ebright
    • The Making of a Scientist This is the story of a young and bright scientist named Richard H. Ebright. He grew up north of Reading, Pennsylvania. At the age of 24 he excited the scientific world with his theory of cells. As a child he collected rocks fossils and coins.
    •  A great driving force in making of him as a scientist  Always encouraged him & developed his interest in learning  Took him on trips  Bought him telescope, microscopes, cameras, mounting materials etc.  Got him the book ‘The Travels of Monarch X’ which opened a new world for him
    • He was her – (i) whole life after his father’s death, (ii) only companion She would find work for him that will make him learn new things, if does not have any some day. He liked it and wanted to learn too.
    • By the time he was in second grade , he had collected all the twenty five species of the butterflies found around his home town in six weeks.
    •  The book is about how butterflies migrate to Central America.  It was written by Dr. Frederick Urquhart of the University of Toronto, Canada.  Readers were invited to help study butterfly migration.  He also asked readers to tag them for research.  This book opened a world of science to this young collector.
    •  But it was impossible to catch so many of them in six weeks.  So he started raising a flock of butterflies in the basement of his house.  He would catch a female monarch, take her eggs and raise them. (Life Cycle)  But as he didn’t get much feedback he started losing interest in it.
    • When he was in the seventh grade, he participated in a science fair and lost. Here he gets a hint of what real science is. He learns that science is not a neat display of something but doing real experiments. He had just shown slides of frog tissues.
    •  He wrote to Dr. Urquhart for ideas and got many suggestions for experiments.  He kept on working on them throughout his high school which led him to many prize projects on national & international levels.  In eighth class he found out the cause of a viral disease that killed all monarch caterpillars. He raised them in presence of beetles.
    •  They are the food of birds.  Viceroys taste good whereas monarchs do not taste good for birds.  The viceroys look like monarchs because they want to trick the birds and save themselves.  This project was placed first in the zoology division.
    •  He tried to find out the purpose of the twelve tiny gold spots on a monarch pupa.  Earlier it was assumed that they were just ornamental.  But later Ebright , along with his fellow students, showed that the spots were producing a hormone necessary for their full development.  It gave him entry in the International Science & Engineering Fair
    •  In his senior year, he grew cells from a monarch’s wings in a culture and showed that the cells would divide and develop into normal butterfly wing scales only if they were fed the hormones from the gold spots.  This project won him the first place for zoology at the international fair.
    •  He studied the photos of the chemical structure of a hormone in the X-ray.  This photo solved his doubt on DNA.  He determined that the DNA is the substance in the nucleus that controls heredity.  So DNA was established to be the blueprint for life.
    •  Richard Ebright became a scientist because he had a driving curiosity along with a bright mind.  He started his journey from collecting the butterflies.  This led him to discover the theory of life cells.  He was not just interested in science.  He took interest in other activities too.
    •  There art many qualities that go into making of a scientist.  He was curious, dedicative and hardworking.  He was competitive but not in a bad sense.  He had a will to win.  He was intelligent and worked for the right reasons.  He didn’t run after prizes.
