I found one english heteronym of Fernando Pessoa. Alexander Search is one of many heteronyms of Fernando Pessoa. It was created in 1899 when Pessoa was a student and was living in South Africa. Under  this name the poet used to write English poems in 1903. I found two poems by Alexander Search.

 Men Of To-day

Men of to-day and yester's nought,

Before you were the things we see

Who gave a guess or gave a mought

That such as you to-day should be?

Ah, passers by the common way,

Who thought of ye before to-day?

Men of to-day, to-morrow's dust,

When years have past where shall ye go?

What vulgar daub or hurried lust

Shall chronicle your joy and woe?

Waves on the crest of life's swift sea,

After to-day who'll think of ye?

Genius alone can cause me fire

That in your glorious nature lies;

Genius alone can strike the lyre

And raíse your name to mortal skies;

Genius of death can tear the pall

And yester's nought mar be an all.

But virtue, fool, like human tears,

By sands of earth too surely drunk,

Sinks in the dust of passing years,

Nor knowest thou where has it sunk.

Let genius then the laurel wear;

To-morrow's dust mar live for e'er.

                                                                  

                                                                 Men of Science

                                           To toil through time and hate and to consume

                                            Far more than life in Error's hard defeat,

                                           Seeking e'er for the true, for the complete,

                                          Careless of faith and misery and doom -

                                           Is there a nobler task, while life doth fleet,

                                          Than this, to strive to make light amid gloom,

                                          And with hands bleeding to part and make room

                                           In tire for weaker and more unsure feet?

                                           The void o'th' world must with an arch be spanned,

                                          The ways of nature must be read aright

                                        That there may be a wise and friendly hand

                                         To make this dark world better and more bright.
