Problem: The answer to the question: What is the last name of the person whose biggest fear was that nothing would happen, in which case he would have to head back to the tower to investigate? is inside the article: Others were less optimistic. Ramsey chose zero (a complete dud), Robert Oppenheimer chose 0.3 kilotons of TNT (1.3 TJ), Kistiakowsky 1.4 kilotons of TNT (5.9 TJ), and Bethe chose 8 kilotons of TNT (33 TJ). Rabi, the last to arrive, took 18 kilotons of TNT (75 TJ) by default, which would win him the pool. In a video interview, Bethe stated that his choice of 8 kt was exactly the value calculated by Segre, and he was swayed by Segre's authority over that of a more junior [but unnamed] member of Segre's group who had calculated 20 kt. Enrico Fermi offered to take wagers among the top physicists and military present on whether the atmosphere would ignite, and if so whether it would destroy just the state, or incinerate the entire planet. This last result had been previously calculated by Bethe to be almost impossible, although for a while it had caused some of the scientists some anxiety. Bainbridge was furious with Fermi for scaring the guards who, unlike the physicists, did not have the advantage of their knowledge about the scientific possibilities. His own biggest fear was that nothing would happen, in which case he would have to head back to the tower to investigate.Julian Mack and Berlyn Brixner were responsible for photography. The photography group employed some fifty different cameras, taking motion and still photographs. Special Fastax cameras taking 10,000 frames per second would record the minute details of the explosion. Spectrograph cameras would record the wavelengths of light emitted by the explosion, and pinhole cameras would record gamma rays. A rotating drum spectrograph at the 10,000-yard (9,100 m) station would obtain the spectrum over the first hundredth of a second. Another, slow recording one would track the fireball. Cameras were placed in bunkers only 800 yards (730 m) from the tower, protected by steel and lead glass, and mounted on sleds so they could be towed out by the lead-lined tank. Some observers brought their own cameras despite the security. Segre brought in Jack Aeby's 35 mm..., can you guess it ?

Problem: The answer to the question: What is the full name of the person who began refortifying the castle in 1296? is inside the article: Brougham Castle (pronounced ) is a medieval building about 2 miles (3.2 km) south-east of Penrith, Cumbria, England. The castle was founded by Robert I de Vieuxpont in the early 13th century. The site, near the confluence of the rivers, Eamont and Lowther, had been chosen by the Romans for a Roman fort called Brocavum. The castle is scheduled as an Ancient Monument, along with the fort, as "Brougham Roman fort and Brougham Castle".In its earliest form, the castle consisted of a stone keep, with an enclosure protected by an earthen bank and a wooden palisade. When the castle was built, Robert de Vieuxpont was one of the only lords in the region who were loyal to King John. The Vieuxponts were a powerful land-owning family in North West England, who also owned the castles of Appleby and Brough. In 1264, Robert de Vieuxpont's grandson, also named Robert, was declared a traitor, and his property was confiscated by Henry III. Brougham Castle and the other estates were eventually returned to the Vieuxpont family, and stayed in their possession, until 1269, when the estates passed to the Clifford family through marriage. With the outbreak of the Wars of Scottish Independence, in 1296, Brougham became an important military base for Robert Clifford, 1st Baron de Clifford. He began refortifying the castle: the wooden outer defences were replaced with stronger, more impressive stone walls, and a large stone gatehouse was added. The importance of Brougham and Robert Clifford was such that, in 1300, he hosted King Edward I of England at the castle. Robert's son, Roger Clifford, was executed as a traitor, in 1322, and the family estates passed into the possession of King Edward II of England, although they were returned once his son Edward III became king. The region was often at risk from the Scots, and in 1388, the castle was captured and sacked., can you guess it ?

A: Robert Clifford

Problem: The answer to the question: What is the last name of the person who worked up until their death? is inside the article: Etty considered Britomart Redeems Faire Amoret one of his major works. Following its exhibition at the 1833 Summer Exhibition, it was exhibited in August of the same year at the Royal Manchester Institution. It was sold at this second exhibition for 157 (about 15,000 in today's terms) to an anonymous collector listed in Etty's records only as "Mr. L., Manchester". It was one of 133 Etty paintings exhibited in a major retrospective exhibition of his work at the Royal Society of Arts in JuneAugust 1849; during this exhibition it was sold on to Lord Charles Townshend for a sum of 520 guineas (about 56,000 in today's terms).Etty died in 1849, having continued working and exhibiting up to his death, and continued to be regarded by many as a pornographer. Charles Robert Leslie observed shortly after Etty's death that "[Etty] himself, thinking and meaning no evil, was not aware of the manner in which his works were regarded by grosser minds". Interest in him declined as new movements came to characterise painting in Britain, and by the end of the 19th century the sales prices achieved by his paintings were falling below the original values., can you guess it ?

A:
Etty
