Why do some people use middle name for their first name like attorneys? And is this ok in the academic venue?
Upon further investigation I found that there are hundreds of thousands of people worldwide who prefer to write their name like the format shown below:
FirstNameInitial + Middle Name + Last Name
It's perfectly legal to use the above format. It's just might not be common for people of your culture or city or state or country to use the above format. Some people may not like their first name or they might share their first name with other family members, so they prefer to use their middle name.
Let's take the example of J. Edgar Hoover, first and former director of FBI.
Full Name: John Edgar Hoover
Surname: Hoover Family Name: Hoover Last Name: Hoover Given Names: John Edgar First Name: John First Given Name: John Middle Name: Edgar Second Given Name: Edgar His name can be written in multiple ways.
John Edgar Hoover John E. Hoover J. Edgar Hoover [known by his First Name Initial and Middle Name] J. E. Hoover John Hoover Edgar Hoover [when the person wants others to call him Edgar] If you are referring to the first and former director of FBI, then please know that all the above formats are applicable. John Edgar Hoover chose to be publicly known as J. Edgar Hoover.
Take the example of M. Night Shyamalan. His legal first name is Manoj and last name is Shyamalan. He prefers to use Manoj "Night" Shyamalan or M. "Night" Shyamalan as his screen / stage name for professional reasons. But he prefers to use a middle name for movies.
Popular people who use middle names include
Sir Thomas Sean Connery Walter Bruce Wills William Bradley "Brad" Pitt Christopher Ashton Kutcher Laura Jeanne Reese Witherspoon Hannah Dakota Fanning John William Ferrel James Paul McCartney Robyn Rihanna Fenty Some people choose pen names like J. K. Rowling. J. K. Rowling's real name is Joanne Rowling. Her pen names are J. K. Rowling and Robert Gailbraith. The letter K in her name is just a letter and not an initial for a middle name. She does not have a middle name. She choose K in memory of her grandmother Kathleen. Alas, her creative imagination and hard work took her to a whole new level. She became one of the world's most popular writers.
Finally, its really up to a person as to how they want to be known.
