Barker cph.3b15338]] '''George Frederick Barker''' (July 14, 1835 – May 24, 1910) was an American [[physicist]] and [[inventor]] known for his contributions to the field of [[electricity]] and [[telegraphy]]. He was a prominent figure in the scientific community during the late 19th and early 20th centuries.<br />
<br />
== Early Life and Education ==<br />
Barker was born in [[Charlestown, Massachusetts]]. He attended the [[Yale University|Sheffield Scientific School]] at [[Yale University]], where he studied under the guidance of [[Benjamin Silliman]], a notable American chemist and geologist. Barker graduated in 1858 with a degree in [[chemistry]].<br />
<br />
== Career ==<br />
After completing his education, Barker held various academic positions. He began his career as a professor of natural science at [[Wheaton College (Massachusetts)|Wheaton College]] in 1858. In 1861, he became a professor of chemistry and physics at the [[Western University of Pennsylvania]], now known as the [[University of Pittsburgh]].<br />
<br />
In 1865, Barker was appointed as a professor of physics at the [[University of Pennsylvania]], where he remained until his retirement in 1900. During his tenure, he conducted significant research in the fields of [[electricity]], [[telegraphy]], and [[spectroscopy]]. Barker was also involved in the development of the [[telephone]] and worked closely with [[Alexander Graham Bell]].<br />
<br />
== Contributions to Science ==<br />
Barker made several notable contributions to science, particularly in the study of electricity. He was one of the first scientists to investigate the properties of the [[electric arc]] and the [[electric spark]]. His work in spectroscopy led to the discovery of several new elements and compounds.<br />
<br />
Barker was also an early advocate for the use of [[electric lighting]] and played a key role in the development of the first electric street lighting systems in the United States. He was a member of several scientific organizations, including the [[American Association for the Advancement of Science]] and the [[National Academy of Sciences]].<br />
<br />
== Personal Life and Legacy ==<br />
Barker married Mary Jane Haggerty in 1860, and they had three children. He was known for his dedication to teaching and his passion for scientific research. Barker passed away on May 24, 1910, in [[Philadelphia, Pennsylvania]].<br />
<br />
Barker's contributions to the field of electricity and his work in advancing scientific knowledge have left a lasting impact. His research and inventions continue to be recognized and celebrated in the scientific community.<br />
