This article reviews the history of peripheral nerve (PN) injuries and successive advances in their management by notable pioneers, an interesting topic that I chose for my Doctoral Thesis in 1990 in Madrid. Mentioning all their names and contributions is an obligatory tribute, and I offer my sincere apologies for inevitably leaving a few out. For half a century I have witnessed microsurgery advances, and also experienced frequent failures in my practice with the use of new techniques; a testimony that we are very far from achieving the 'Holy Grail' of complete PN recovery for these injuries. Our experience is often like a pendulum, from nihilism to optimism and vice versa. Many factors influence the results of PN repair. Fortunately, microsurgery has been a breakthrough but, too often, emergency surgery is carried out by surgeons without enough tools and experience, both very important factors in this field.
