Given the question: What is the first name of the person who had studied Watts's Hope in the 1950s, and had rediscovered the painting when Dr Frederick G. Sampson delivered a lecture on it in the late 1980s?  Answer the above question based on the context below:  Despite the steep decline in Watts's popularity, Hope continued to hold a place in popular culture, and there remained those who considered it a major work. When the Tate Gallery held an exhibition of its Watts holdings in 1954, trade unionist and left-wing M.P. Percy Collick urged "Labour stalwarts" to attend the exhibition, supposedly privately recounting that he had recently met a Viennese Jewish woman who during "the terrors of the Nazi War" had drawn "renewed faith and hope" from her photographic copy. Meanwhile, an influential 1959 sermon by Martin Luther King Jr., now known as Shattered Dreams, took Hope as a symbol of frustrated ambition and the knowledge that few people live to see their wishes fulfilled, arguing that "shattered dreams are a hallmark of our mortal life", and against retreating into either apathetic cynicism, a fatalistic belief in God's will or escapist fantasy in response to failure.Myths continued to grow about supposed beliefs in the redemptive powers of Hope, and in the 1970s a rumour began spread that after Israel defeated Egypt in the Six-Day War, the Egyptian government issued copies of it to its troops. There is no evidence this took place, and the story is likely to stem from the fact that in early 1974, shortly after the Yom Kippur War between Israel and Egypt, the image of Hope appeared on Jordanian postage stamps. Likewise, it is regularly claimed that Nelson Mandela kept a print of Hope in his cell on Robben Island, a claim for which there is no evidence.In 1990 Barack Obama, at the time a student at Harvard Law School, attended a sermon at the Trinity United Church of Christ preached by Jeremiah Wright. Taking the Books of Samuel as a starting point, Wright explained that he had studied Watts's Hope in the 1950s, and had rediscovered the painting when Dr Frederick G. Sampson delivered a lecture on it in the late 1980s (Sampson described it as "a study in contradictions"), before discussing the image's significance in the modern world.
The answer is:
