Which accomplishments was NOT Matthew Fontaine Maurys?

Matthew Fontaine Maury is best known for his contributions to oceanography, particularly the development of charts and navigation techniques based on ocean currents and winds. However, he did not invent the steam engine; that invention is attributed to figures like James Watt and others in the 18th century. Maury's work was focused on improving maritime navigation and understanding the seas rather than developing steam technology.
