Here's why:
* Samuel Johnson (1709-1784) was an English writer, poet, essayist, moralist, literary critic, and lexicographer. He is best known for his Dictionary of the English Language, published in 1755.
* Noah Webster (1758-1843) was an American lexicographer, textbook writer, and political writer. He is known for his American Dictionary of the English Language, published in 1828, which aimed to standardize American English.
Their lives and work overlapped, but there is no evidence of any interaction between them. Their different national contexts, differing approaches to lexicography, and the time difference between their major works (Johnson's dictionary published in 1755, Webster's in 1828) all contribute to the lack of any connection.
While they both contributed significantly to the English language, they were individual figures with distinct goals and influences.
