What is the diameter of the Shapley supercluster?
Super clusters do not have defined boundaries, not a defined shape. A ballpark figure would put the diameter at about 100 million light years, but extending to about 250 million light years at the extreme. See related link for a pictorial of the cluster
Who was the first astronomer to get a reasonable idea of the size and shape of the galaxy?
Shapley
Who was George E. Hale and what did he discover?
George Ellery Hale (June 29, 1868 - February 21, 1938) was an American solar astronomer, born in Chicago. He was educated at MIT, at the Observatory of Harvard College, (1889-90), and at Berlin (1893-94). As an undergraduate at MIT, he invented the spectroheliograph, with which he made his discoveries of the solar vortices and magnetic fields of sun spots. In 1890 he was appointed director of the Kenwood Astrophysical Observatory; he was professor of Astrophysics at Beloit College (1891-93); associate professor at the University of Chicago until 1897, and full professor (1897-1905). He was coeditor of Astronomy and Astrophysics, 1892-95, and after 1895 editor of the Astrophysical Journal. Hale was a driven individual who worked to found a number of significant astronomical observatories, including Yerkes Observatory, Mount Wilson Observatory, Palomar Observatory, and the Hale Solar Laboratory. At Mount Wilson, he hired and encouraged Harlow Shapley and Edwin Hubble toward some of the most significant discoveries of the time. He was a prolific organizer who helped create a number of astronomical institutions, societies and journals. Hale also played a central role in developing the California Institute of Technology into a leading research university.
How did Harlow Shapley determine where the center of the galaxy lies?
by plotting the distribution of open clusters
What did Harlow Shapley discover?
Harlow Shapley studied globular clusters and used the position of the clusters to locate the sun in the middle of our galaxy. He found out he was wrong but figured out that the sun was in one of the spiral arms in our galaxy
What main conclusion did Shapley draw from his measurements of the distances to the globular clusters?
The sun is far from the center of the Milky Way.

Is there a school named after Harlow shapley?
Not quite. There was a school in ridgefield CT name The Shapley School that was named after Dr. Harlow Shapley's son, Carl Shapley. Carl Shapley was the headmaster. A very strange little school that I attended for one year in the 1960s. I think the scholl lasted about 5 or 6 years. Pardon the typos!
