The monster vertex algebra (or moonshine module) is a vertex algebra acted on by the monster group that was constructed by Igor Frenkel, James Lepowsky, and Arne Meurman. R. Borcherds used it to prove the monstrous moonshine conjectures, by applying the Goddard–Thorn theorem of string theory to construct the monster Lie algebra, an infinite-dimensional generalized Kac–Moody algebra acted on by the monster. The Griess algebra is the same as the degree 2 piece of the monster vertex algebra, and the Griess product is one of the vertex algebra products. It can be constructed as conformal field theory describing 24 free bosons compactified on the torus induced by the Leech lattice and orbifolded by the two-element reflection group. (Wikipedia).
This is a historical talk giving my recollections of how vertex algebras were discovered. It was requested by Michael Penn for his series of videos on vertex algebras https://www.youtube.com/playlist?list=PL22w63XsKjqyx2FFUywi_mz91Jtih52yX

A gentle description of a vertex algebra.
Working from the notions of associative algebras, Lie algebras, and Poisson algebras we build the idea of a vertex algebra. We end with the proper definition as well as an "intuition" for how to think of the parts. Please Subscribe: https://www.youtube.com/michaelpennmath?sub_confirmation

Some reasons why vertex algebras are interesting.
We give some reasons why anyone would want to study vertex algebras. We include their connection to group theory, number theory, and mathematical physics. More VOAs on youtube: https://www.youtube.com/c/seandownes/playlists Please Subscribe: https://www.youtube.com/michaelpennmath?sub_co

We give some examples of the types of vector spaces it is important to be comfortable with in order to study vertex algebras. We look at three main example, a polynomial ring in infinitely many variables, the exterior algebra of infinitely many variables, and the universal enveloping algeb
