 In 1890, Ebbinghaus came up with the double pyramid design where corners were rounded off.Unlike notable contemporaries like Titchener and James, Ebbinghaus did not promote any specific school of psychology nor was he known for extensive lifetime research, having done only three works.He never attempted to bestow upon himself the title of the pioneer of experimental psychology, did not seek to have any "disciples", and left the exploitation of the new field to others.
