In this talk I shall try to outline the subject which will be discussed in detail by the succeeding speakers. I shall concentrate on ideas and I shall not attempt to present any definite results. The two sides to this problem are:

(a) How much helium is there in the Universe?

and

(b) Where and how has it been produced?

I shall sub-divide (a) and (b) into

  • (a) (i) Direct observations

    • (ii) Inferences from theories of stellar structure and evolution

  • (b) (i) Helium production in stars

    • (ii) Primeval helium production

    • (iii) Production in other objects
