St. Albert the Great. Long story short, this Medieval German fellow was an uber-scholar known for his wide interest in the natural sciences and his encyclopedic knowledge. Member of the Order of Friars Preachers. Was a bishop, writer, teacher and of course a preacher. Canonized and made Doctor of the Church in 1931, a short 651 years after his death (remember this the next time you think the Holy See is taking their sweet time advancing the canonization of your favorite modern candidate for sainthood).
He is a patron of philosophers, scientist and students
Sanctus Albertus, ora pro nobis
