As an addendum, here are anime that I would consider quintessential, spanning from the 60s to the end of the 70s. Reasoning or episode guides included
>Tetsuwan Atom
Specifically the key creative episodes, your Dezakis and Tominos and whoever else you're interested in.
>Dororo to Hyakkimaru
First TV anime that makes great leaps in pursuit of a form of artistic integrity, like the B&W used for both censorship and as an artistic statement.
>Ashita no Joe
Should be obvious.
>Lupin III Part I & Mystery of Mamo
Quintessential early Lupin, just well rounded and highly influential works in general.
>Ace wo Nerae
>Gamba no Bouken
>Nobody's Boy Remi
>Takarajima
All incredibly significant Osamu Dezaki anime.
>Rose of Versailles
Dezaki and Nagahama work.
>Kyojin no Hoshi
The quintessential Nagahama work.
>Voltes V
>Daimos
>Combattler V
The Robot Romance trilogy, highly influential and significant to the burgeoning 'maturation' of the mecha genre.
>Zambot 3
Also plays a role in this and shows the roots of Tomino's more aggressive stylings as a writer. Adjacent to that are
>Daitarn 3
>Mobile Suit Gundam
Further quintessential Tomino works.
>Moomin (1969, 1972)
>Rocky Chuck
>Apls no Shoujo Heidi
>Dog of Flanders
>Rascal
>3000 Leagues in Search of Mother
>Anne of Green Gables
These are the most significant WMT works outside Dororo to Hyakkimaru of the 60s-70s. It's a lot, but WMT is fairly backloaded in significance- in particular, Heidi, Flanders, and Anne are key works that you see influencing a lot to come (in particular, Anne's characterization holds a lot of influence in later works like Doremi or Princess Tutu, for example).
>Uchuu Senkan Yamato
>Captain Harlock
>Galaxy Express 999
These are the key Leiji Matsumoto adaptations of the 70s and probably the first instance of a stylistically consistent and driven creative mind backing a set of projects.

There's far more works than this, I only offer a mere taste.
