Paul de Rousiers (16 January 1857 – 28 March 1934) was a French social economist and industrial lobbyist. He was a follower of Pierre Guillaume Frédéric le Play, and believed in industrial syndicates that would be independent of both workers and owners, and would be dedicated to the progress of their industries. He undertook studies of society and economic organization in the United States, Britain and Germany, where he visited the rural areas, towns, cities, farms, mines and factories, and spoke to workers, owners, politicians and intellectuals to gain an understanding of the interplay of social and economic forces. His work gained him considerable respect. In 1903 Paul de Rousiers became secretary-general of the French shipowners' association, a position he held for most of the rest of his life. In this role he proved a highly effective lobbyist. He also provided valuable information and legal services to the members, and helped in their negotiations with trade unions. He remained involved in social economics, and taught a course at the École libre des sciences politiques. Paul de Rousiers was a prolific author throughout his career, publishing many books and articles. Source: Wikipedia (en)
