What was Robert Weaver's title when he became a presidential cabinet member?

Robert Weaver served as the first Secretary of Housing and Urban Development (HUD) when he became a member of President Lyndon B. Johnson's cabinet. Appointed in 1966, Weaver was pivotal in shaping urban policies and addressing housing issues, particularly in the context of the Great Society programs aimed at combating poverty and improving living conditions in urban areas. His role was significant as it marked the first time an African American was appointed to a cabinet position in the United States, highlighting a step towards greater diversity and representation in federal government.

The other titles listed are associated with different historical figures or roles within the cabinet at various times, but none correspond to Weaver’s significant position in housing reform and urban development.
