What were the first anime based on manga and light novels?


I know that original animes weren't based on light novels or mangas (see:
[this](https://anime.stackexchange.com/questions/3408/what-is-the-first-ever-
produced-anime-and-manga)). However, I think there are some early shows that
are based on mangas (Astro Boy for example, I think). What was the first anime
based on a manga? Also, what was the first anime based on a light novel?




While not the most scientific method, one could generate a list of anime
entries over at [Anime News Network](http://www.animenewsnetwork.com/), sort
it by order and see what is the earliest entry in their database that fits the
criterion we're looking for. [Here would be an example of such a
list.](http://www.animenewsnetwork.com/encyclopedia/anime-
list.php?showdate=1&limit_to=&showT=1&showO=1&licensed=&sort=date)

Obviously the service's database is most likely incomplete, but regardless, it
is still an authoritative source for anime information, and given the size,
and time range of the database, it can be trusted as a good estimation.
