Paul Rand is known as one of the greatest graphic designers to ever live. He designed logos that we see everyday like, IBM, ABC, UPS and thats only a few.
This is the original logo for UPS that was made in 1961 by Rand
The IBM logo is probably Rands most famous peace of work that he created in 1962.
The ABC logo was made in 1962 and the one we see today still uses the same basic design that Rand created years ago.
