Question: Which contributor to Padrón Real was the first to demonstrate that Columbus' conjecture about Asia's eastern outskirts was wrong?

The Richmond–Petersburg Campaign was a series of battles around Petersburg, Virginia, fought from June 9, 1864, to March 25, 1865, during the American Civil War.  Although it is more popularly known as the Siege of Petersburg, it was not a classic military siege, in which a city is usually surrounded and all supply lines are cut off, nor was it strictly limited to actions against Petersburg.  The campaign consisted of nine months of trench warfare in which Union forces commanded by Lt. Gen. Ulysses S. Grant assaulted Petersburg unsuccessfully and then constructed trench lines that eventually extended over 30 mi from the eastern outskirts of Richmond, Virginia, to around the eastern and southern outskirts of Petersburg.  Petersburg was crucial to the supply of Confederate Gen. Robert E. Lee's army and the Confederate capital of Richmond.  Numerous raids were conducted and battles fought in attempts to cut off the Richmond and Petersburg Railroad.  Many of these battles caused the lengthening of the trench lines, overloading dwindling Confederate resources. <SEP> Amerigo Vespucci (] ; March 9, 1454February 22, 1512) was an Italian explorer, financier, navigator and cartographer who first demonstrated that Brazil and the West Indies did not represent Asia's eastern outskirts as initially conjectured from Columbus' voyages, but instead constituted an entirely separate landmass hitherto unknown to people of the Old World. <SEP> In mathematics, Blattner's conjecture or Blattner's formula is a description of the discrete series representations of a general semisimple group "G" in terms of their restricted representations to a maximal compact subgroup "K" (their so-called "K"-types).  Harish-Chandra orally attributed the conjecture to Robert J Blattner as a question Blattner raised, not a conjecture made by Blattner.  Blattner did not publish it in any form.  It first appeared in print in , where it was first referred to as "Blattner's Conjecture," despite the results of that paper having been obtained without knowledge of Blattner's question and notwithstanding Blattner's not having made such a conjecture.  mentioned a special case of it slightly earlier.  proved Blattner's formula in some special cases, showed that Blattner's formula gave an upper bound for the multiplicities of "K"-representations, proved Blattner's conjecture for groups whose symmetric space is Hermitian, and proved Blattner's conjecture for linear semisimple groups.  Blattner's conjecture (formula) was also proved by by infinitesimal methods which were totally new and completely different from those of Hecht and Schmid (1975).  Part of the impetus for Enright’s paper (1979) came from several sources: from , , .  In Enright (1979) multiplicity formulae are given for the so-called mock-discrete series representations also.  used his ideas to obtain deep results on the construction and classification of irreducible Harish-Chandra modules of any real semisimple Lie algebra. <SEP> The Padrón Real (] , "Royal Register"), known after 2 August 1527 as the Padrón General (] , "General Register"), was the official and secret Spanish master map used as a template for the maps present on all Spanish ships during the 16th century.  It was kept in Seville, Spain by the Casa de Contratación.  Ship pilots were required to use a copy of the official government chart, or risk the penalty of a 50 doblas fine.  Well known official cartographers and pilots who contributed to and used the map included Amerigo Vespucci, Diogo Ribeiro, Sebastian Cabot, Alonzo de Santa Cruz, and Juan Lopez de Velasco.  The map probably included a large-scale chart that hung on the wall of the old Alcazar in Seville.
