The progressives were those who contributed to make changes in society and living style. They were ready to betray their own lives to make changes in the environment of the country. I believe that in the progressive era, there were three major progressives who deserve to be the hall of fame: Jane Addams, Upton Sinclair, Samuel M. Jones. I think these progressives deserve more than other progressive because they did things those other progressives would follow. It can be said that these reformers are examples of the progressive spirit.
Jane Addams dedicated her whole life to help the urban poor. Before that she tirelessly worked for women's suffrage and became the president of the Women's International League for Peace and Freedom form 1919 to 1935. Because of her hard work she got recognized internationally and won the Nobel Peace Prize. Also, she established the settlement house, community centers in poor neighborhood that provided education, recreation, and other services. She and Ellen Gates Starr established Hull House mission that was to provide a center for a higher civic and social life and to investigate and improve the conditions in the industrial districts of Chicago. She made an example for other progressive to follow so I think she deserves to have a spot in the Progressive Hall of Fame.
Another dedicated nationalist progressive Upton Sinclair was a great and persuasive muckraker. He wrote more than a hundred books about unsanitary condition, political bosses and corruption to open the eyes of the citizen. In 1906 Upton Sinclair published The Jungle, his most famous novel about the meat-packing industry in Chicago. In response to this book Americans demanded federal laws prohibiting unhealthful conditions in food-processing industries and more than half of people who read this book became vegetations. As soon as Roosevelt read this book he persuaded congress to get Pure Food and Drug Act and Meat Inspection Act.
