The Kantian influence is pervasive throughout Heidegger's most celebrated and influential book, Being and Time (1927).

However, the main source for the Kantbook was Heidegger's encounter with Ernst Cassirer in Davos, in 1929.

It is here Heidegger begins to develop his unique interpretation of Kant which places unprecedented emphasis on the schematism of the categories.

Heidegger began writing Kant and the Problem of Metaphysics immediately after Davos.
