Jacob Riis: A Reporter Who Fought for the Poor in Old New York



I'm Shirley Griffith. And I'm Ray Freeman with the VOA Special English program, PEOPLE IN AMERICA.
Every week at this time, the Voice of America tells about someone important in the history of the United States. This week we tell about Jacob Riis. He was a writer who used all his energy to make the world a better place for poor people.
(MUSIC)
In the spring of eighteen seventy, a young man traveled across the Atlantic Ocean to New York City. The young man came from Denmark. His name was Jacob Riis. He was just twenty-one years old.
His first years in the United States were difficult, like those of most immigrants at that time. It was difficult to get a job. Jacob Riis went from place to place seeking work. He did any kind of work he could find. Farming, coal mining, brick-making. He even tried to earn money as a peddler. He went from house to house selling things. Many times he slept wherever he could.
Soon he was beginning to lose hope. He decided to leave New York. He started to walk north. After a time, he arrived in the Bronx, the northern part of New York City. His feet burned with pain. And he was hungry.
"I had not eaten a thing since the day before. I had no breakfast, and decided to have a swim in the Bronx River, instead. But that did not help. I was just as hungry when I came out of the water.
"Then I walked slowly to Fordham College, which was not far from where I was. The doors to Fordham College were open, and I walked in, for no reason. I was just tired and had nothing else to do.
"Fordham is a Catholic college. And an old monk came to me and asked in a kind voice if I was hungry. I still remember in my dreams at night the beautiful face of that old monk. I was terribly hungry, and said I was, although I did not mean to do so. I had never seen a real live monk before. My own religious education as a Lutheran did not teach me to like Catholic monks.
"I ate the food that was brought to me. But I was troubled. I was afraid that after giving me food, the churchman would ask me to change my religious beliefs. I said to myself: 'I am not going to do it. ' But when I had eaten, I was not asked to do anything. I was given more food when I left, and continued on my way. I was angry with myself for having such bad thoughts about the Catholic churchmen at Fordham College. For the first time, I learned something about how to live with people of different religious beliefs."
(MUSIC)
Later, Jacob Riis learned more about liking people, even if they are different. This time, it happened while he was working on a railroad with men who did rough work and looked rough.
"I had never done that sort of work, and it was not the right job for me. I did my best to work like the other men. But my chest felt heavy, and my heart pounded in my body as if it were going to explode. There were nineteen Irishmen in the group. They were big, rough fellows. They had chosen me as the only 'Dutchman' -- as they called me -- to make them laugh. They were going to use me as part of their jokes.
"But then they saw that the job was just too hard for me. This made them feel different about me. It showed another side to these fun-loving, big-hearted people. They thought of many ways to get me away from the very rough work. One was to get me to bring water for them. They liked stronger things to drink than water. But now they suddenly wanted water all the time. I had to walk a long way for the water. But it stopped me from doing the work that was too hard for me. These people were very rough in their ways. But behind the roughness they were good men. "
At last, Jacob Riis got a job writing for a newspaper in New York City. This was his chance. He finally had found a profession that would lead to his life work -- making the world a better place for poor people.
The newspaper sent him to police headquarters for stories. There he saw life at its worst, especially in a very poor part of New York which was known as Mulberry Bend.
"It was no place for men and women. And surely no place for little children. It was a terrible slum -- as such places are called -- where too many are crowded together, where the houses and streets are dirty and full of rats. The place began to trouble me as the truth about it became clear. Others were not troubled. They had no way of finding out how terrible the lives of people were in Mulberry Bend. But as a newspaper reporter, I could find the truth. So I went through the dark dirty streets and houses, and saw how the people suffered in this area. And I wrote many stories about the life there.
"I did good work as a police reporter, but wanted a change. My editor said, 'no'. He asked me to go back to Mulberry Bend and stay there. He said I was finding something there that needed me."
The words of Jacob Riis' editor proved to be very true. Riis started a personal war against slum houses, the sort he saw in Mulberry Bend. He learned to use a camera to show the public clearly what the Mulberry Bend slum was like. The camera in the eighteen eighties was nothing like it is today. But Riis got his pictures.
"I made good use of them quickly. Words could get no action to change things. But the pictures did. What the camera showed was so powerful that the city's health officials started to do something. At last I had a strong partner in the fight against Mulberry Bend -- my camera. "
(MUSIC)
Jacob Riis continued the fight to clean up the slums for many years. There were not many people to help him. It was a lonely fight. But his camera and fighting words helped to get a law passed which would destroy the Mulberry Bend slum. Finally, the great day came. The slum housing was gone. The area had become a park.
"When they had fixed the ground so the grass could grow, I saw children dancing there in the sunlight. They were going to have a better life, thank God. We had given them their lost chance. I looked at these dancing children and saw how happy they were. This place that had been full of crime and murder became the most orderly in the city.
"The murders and crimes disappeared when they let sunlight come into the Bend. The sunlight that shone upon children who had, at last, the right to play. That was what the Mulberry Bend Park meant. So the Bend went. And I was very happy that I had helped to make it go. "
That was not Riis' last battle to make life cleaner and better for many people. He had great energy. And his love for people was as great as his energy.
He started a campaign to get clean water for the state of New York. He showed that water for the state was not healthy for people. State officials were forced to take actions that would clean the water.
He also worked to get laws against child labor, and made sure that these laws were obeyed. In those days, when Riis was a fighting newspaper reporter, laws against child labor were something new. People did not object to making young children work long hours, in places that had bad air and bad light. But in the United States today, child labor is not legal. It was because of men like Jacob Riis that this is so.
He was also successful in getting playgrounds for children. And he helped establish centers for education and fun for older people.
His book, "How the Other Half Lives," was published in eighteen ninety. He became famous. That book and his newspaper reports influenced many people. Theodore Roosevelt, who later became president of the United States, called Riis the most useful citizen in New York City.
Riis continued to write about conditions that were in need of major reform. His twelve books including "Children of the Poor" helped improve conditions in the city. The books also made him popular as a speaker in other cities. Jacob Riis's concern for the poor kept him so busy writing and speaking around the country that he ruined his health. He died in nineteen fourteen.

Albert Einstein

Albert Einstein (1879-1955)

This is Steve Ember. And this is Sarah Long with the VOA Special English program,EXPLORATIONS.
Today we tell about a scientist who changed the way we understand the universe, Albert Einstein.
(MUSIC)
In the year 1905, Albert Einstein published some important papers in a German scientific magazine. They included one of the most important scientific documents in history. It was filled with mathematics. It explained what came to be called his "Special Theory of Relativity." Ten years later he expanded it to a "General Theory of Relativity."
Albert Einstein's theories of relativity are about the basic ideas we use to describe natural happenings. They are about time, space, mass, movement, and gravity.
Albert Einstein was born in Ulm, Germany, in 1879. His father owned a factory that made electrical devices. His mother enjoyed music and books. His parents were Jewish but they did not observe many of the religion's rules.
Albert was a quiet child who spent much of his time alone. He was slow to talk and had difficulty learning to read.
When Albert was five years old, his father gave him a compass. The child was filled with wonder when he discovered that the compass needle always pointed in the same direction -- to the north. He asked his father and his uncle what caused the needle to move.
Their answers about magnetism and gravity were difficult for the boy to understand. Yet he spent a lot of time thinking about them. He said later that he felt something hidden had to be behind things.
Albert did not like school. The German schools of that time were not pleasant. Students could not ask questions.  Albert said he felt as if he were in prison.
One story says Albert told his Uncle Jacob how much he hated school, especially mathematics. His uncle told him to solve mathematical problems by pretending to be a policeman. "You are looking for someone," he said, "but you do not know who. Call him X. Find him by using the mathematical tools of algebra and geometry."
Albert learned to love mathematics. He was studying the complex mathematics of calculus when all his friends were still studying simple mathematics. Instead of playing with friends he thought about things such as: "What would happen if people could travel at the speed of light?"
Albert decided that he wanted to teach mathematics and physics. He attended the Federal Polytechnic Institute in Zurich, Switzerland. He graduated with honors, but could not get a teaching job. So he began working for the Swiss government as an inspector of patents for new inventions. The job was not demanding. He had a lot of time to think about some of his scientific theories.
From the time he was a boy, Albert Einstein had performed what he called "thought experiments" to test his ideas. He used his mind as a laboratory. By 1905, he had formed his ideas into theories that he published.
In one paper he said that light travels both in waves and in particles, called photons. This idea is an important part of what is called the quantum theory.
Another paper was about the motion of small particles suspended in a liquid or gas. It confirmed the atomic theory of matter.
The most important of Albert Einstein's theories published that year became known as his "Special Theory of Relativity." He said the speed of light is always the same -- almost three hundred thousand kilometers a second. Where the light is coming from or who is measuring it does not change the speed. However, he said, time can change. And mass can change. And length can change. They depend on where a person is in relation to an object or an event.
Imagine two space vehicles with a scientist travelling in each one. One spaceship is red. One is blue. Except for color, both spaceships are exactly alike. They pass one another far out in space.
Neither scientist feels that his ship is moving. To each, it seems that the other ship is moving, not his. As they pass at high speed, the scientist in each ship measures how long it takes a beam of light to travel from the floor to the top of his spaceship, hit a mirror and return to the floor. Each spaceship has a window that lets each scientist see the experiment of the other.
They begin their experiments at exactly the same moment. The scientist in the blue ship sees his beam of light go straight up and come straight down. But he sees that the light beam in the red ship does not do this. The red ship is moving so fast that the beam does not appear to go straight up. It forms a path up and down that looks like an upside down "V".
The scientist in the red ship would see exactly the same thing as he watched the experiment by the other scientist. He could say that time passed more slowly in the other ship. Each scientist would be correct, because the passing of time is linked to the position of the observer.
Each scientist also would see that the other spaceship was shorter than his own. The higher the speeds the spaceships were travelling, the shorter the other ship would appear. And although the other ship would seem shorter, its mass would increase. It would seem to get heavier.
The ideas were difficult to accept. Yet other scientists did experiments to prove that Einstein's theory was correct.
Ten years after his paper on the special theory of relativity, Albert Einstein finished work on another theory. It described what he called his "General Theory of Relativity." It expanded his special theory to include the motion of objects that are gaining speed. This theory offered new ideas about gravity and the close relationship between matter and energy. It built on the ideas about mass he had expressed in 1905.
Einstein said that an object loses mass when it gives off light, which is a kind of energy. He believed that matter and energy were different forms of the same thing. That was the basis of his famous mathematical statement E equals m-c squared (energy equals mass times the speed of light squared). This statement or formula explained that a great amount of energy could come from a small piece of matter. It explained how the sun could give off heat and light for millions of years. This formula also led to the discovery of atomic energy.
In his general theory of relativity, Einstein said that gravity, like time, is not always the same. Gravity changes as observers speed up or slow down. He also said that gravity from very large objects, such as stars, could turn the path of light waves that passed nearby. This seemed unbelievable. But in 1919, British scientists confirmed his theory when the sun was completely blocked during a solar eclipse. Albert Einstein immediately became famous around the world.
In 1921, he won the Nobel Prize in Physics. It was given to him, not for his theories of relativity, but for his discovery of the law of the photoelectric effect. This scientific law explained how and why some metals give off electrons after light falls on their surfaces. The discovery led to the development of modern electronics, including radio and television.
Albert Einstein taught in Switzerland and Germany. He left Germany when Adolph Hitler came to power in 1933. He moved to the United States to continue his research. He worked at the Institute for Advanced Study in Princeton, New Jersey. Einstein became a citizen of the United States in 1940.
Einstein was a famous man, but you would not have known that by looking at him. His white hair was long and wild. He wore old clothes. He showed an inner joy when he was playing his violin or talking about his work. Students and friends said he had a way of explaining difficult ideas using images that were easy to understand.
Albert Einstein opposed wars. Yet he wrote to President Franklin Roosevelt in 1939 to advise him that the United States should develop an atomic bomb before Germany did.
Einstein spent the last twenty-five years of his life working on what he called a "unified field theory." He hoped to find a common mathematical statement that could tie together all the different parts of physics. He did not succeed.
Albert Einstein died in 1955. He was seventy-six years old.
