To elaborate on the answer by @Fls’Zen, yes the proper method is to enclose the name in double-quotes.
From a practical point of view there’s no harm in wrapping all names in double-quotes, just be sure to escape a double-quote if it appears in the display name \" (or just replace with a single-quote). But if you want to be completely by the spec, you shouldn’t use the double quotes if you don’t have to.
For all the dense details, E-mail header fields are defined by RFC 5322. The relevant section for multiple originators in the From header is 3.6.2, and the relevant sections for quoting delimiters is 3.2.1 and 3.2.4.
