Who invented portable the first type writer?

The invention of the first portable typewriter is generally credited to L. C. Smith Brothers in 1912. While other inventors had created smaller typewriters before, the L. C. Smith & Bros. Typewriter Company's model was the first to be marketed specifically as a portable option.

It's important to note that there were other significant developments in portable typewriter technology:

* 1886: The Hammond Typewriter Company introduced a smaller, more portable typewriter, though not as widely available or successful as the later L.C. Smith models.

* 1918: The Corona Typewriter Company released the Corona 3, a lightweight and compact typewriter that became a popular choice for writers and travelers.

So, while L.C. Smith Brothers are credited with the first commercially successful portable typewriter, the development of this technology involved various inventors and companies.
