LA TROBE in Melbourne

Walking down Latrobe St in Melbourne, I came across this chap named 'LA TROBE' standing outside the State Library.

Who was he?
Why the book?

What contribution did he make to have a statue, and a road named in his honour?

Update:
Melbourne, Who Do You Think You Are?

Charles La Trobe 1801-1874, appointed Superintendent of Port Phillip District (1839) then the first Lieutenant-Governor of the Colony of Victoria (51-54).
Well intended, yet under skilled for his positions; he increased taxes, didn't care for Indigenous people well, was attributed to the Eureka Stockade, and with the Colony in financial hardship and fermenting social problems he returned to England 1854.

A supporter of religious, cultural and educational institutions, hence the book, he was accredited for the Botanic Gardens & hospital.
Also named after him; a university, a suburb, the Latrobe Valley region, Mount Latrobe in Wilson's Prom, his home Latrobe's Cottage has been preserved in Jolimint on land he purchased at auction for £20 an acre because the residents agreed not to bid against him.

La Trobe, reads like a modern politician -
I was expecting better.
