Is Ibn al-Qayyim the same as Ibn al-Jawzi?

Ibn al-Qayyim is the eminent scholar Shams al-Din Muhammad ibn Abi Bakr al-Zura'i. He was a close student of his shaykh, Taqi al-Din Ibn Taymiyyah, and acquired a great deal of knowledge from him. He was described as unique in the various branches of knowledge, very devout, of excellent character, free from envy towards anyone, and very amiable. He used to prolong his prayers considerably, authored many works, wrote extensively in his own hand, and acquired a collection of books that no one else could hope to obtain even a tenth of.
