Side note but maybe interesting. As many writers, Pessoa worked in a variety of occupations and wrote the first portuguese Coca-Cola slogan. Pessoa wrote the following slogan for Coca-Cola:
"Primeiro estranha-se. Depois entranha-se"
In my opinion it is a great slogan, but it's very hard to translate and must be appreciated in the native language. Most translations are wrong. This was in the 20's, and Portugal was already under press censorship, and what would be a 50 years dictatorship. Lisbon's director of Health at the time had Coca-Cola banned on the premises:
"- If one of the ingredients is coca, from which cocaine is extracted, then the product can't be sold so as to not intoxicate the public.
- If the product does not have coca, then selling it under that name to get customers is fraud; hence, it cannot be sold.
- Pessoa recognized its toxicity, for his slogan was very specific. Not liking a substance at first but then getting used to it is a characteristic of drugs.
And so Pessoa inadvertently sealed Coca-Cola's fate in Portugal for the following decades..."

Edit:
Another interesting point that if you are new to Pessoa
you might not know, is that the writers Alberto Caeiro, Álvaro de Campos and Ricardo Reis are also Fernando Pessoa! His creativity could not be captured simply via one identity so he created heteronyms, and their style is quite different. He also used more than 70 pseudonyms but those the style still is Pessoa.
Note I refer to Heteronym as in literature not as in Linguistics:
