Ernest Nagel (1901-1985), one of the most prominent philosophers of science in the 20th century, argued most strongly for the connection between philosophy and science.
His book, The Structure of Science: Problems in the Logic of Scientific Explanation (1961) is a classic of the field.
In the Encyclopedia of Philosophy, H. S. Thayes writes it is a masterly and complete exposition of his
analysis of explanation, the logic of scientific inquiry, and the logical structure of the organization of scientific knowledge, and it illuminates the cardinal issues concerning the foundation and the assessment of explanation in physics and in the biological and social sciences.
