Oscar Hertwig
Born and Deceased:
Born: April 21, 1849 in Friedberg Germany.
Deceased: October 25, 1922 in Berlin Germany.
Most of his research spanned between 1881 - 1921
What did he do?
Oscar studied Embryology, and fertilization, specifically of the sea urchin. He did this because the animal is transparent and he could see the sperm fertilize the egg which gave him a greater understanding of animal fertilization as a whole. Doing this gave him the chance to look deeper and research the behavior of chromosomes and how they work with meiosis. This further advanced the knowledge and studies of reproduction and genetic makeup involving chromosomes.
Other events in the time:
- World War I - Large event going on between 1914 - 1918
- Controversy between his research and others, until it was concluded that chromosomes exchanged genes by crossing over.
- Ernst Haeckel went to the Mediterranean to research with Oscar and his brother which led him to study the sea urchin.
So what made him successful while others not?
His experiment and research.
Having able to research on the sea urchin made him many steps ahead of the other scientists because he was able to visually backup his data, and research with more detail. Also having something he could do experiments on helped him be able to get better data. When others may have an animals sperm cell or an egg cell and not be able to see specifically how they interact.
When Ernst Haekel and the two Hertwig brothers went to study at in the Mediterranean, Oscar found that the sea urchin is transparent and he could use it to further his research. When he would look at the sea urchin and its behaviors he was able to see specifically the sperm and egg cells. This then enhanced his view on chromosomes and the passing of genetic DNA.
His contribution to future biology and other scientists research.
Gaining the new knowledge of fertilization and the passing on of genetic makeup through chromosomes really put the whole topic a step foreword. Because having the controversy at the time he was doing research may have led to more proven results after his by other scientists.
