What the World’s Greatest Orators Teach Us About Public Speaking
Demosthenes
Demosthenes was the greatest orator of ancient Greece and is regarded as a great master in oratory in history. His life story is highly inspiring to everyone who is aspiring to become an orator. His childhood was extremely pathetic and miserable. He was brought up by women in the family since his father was far away from home. He did not get the love, affection, and care of his parents as other children of his age. He became extremely lonely and isolated and hence he found solace in the world of books.
He was very pale, unhealthy and feeble. He was worried about his stammering. Yet, his greatest desire was to become an orator and he took a firm decision to overcome his defects at any cost. He started to work hard for fulfilling his desire. He regularly went to the seashore and spoke to the waves loudly, after putting pebbles in his mouth. He used to run up to the hills and down the valleys, speaking or singing to his maximum voice. He wanted to overcome his tiredness and difficulty in speaking loudly and fluently at difficult situations.
Gradually he gained the confidence to face people and to speak fluently. He dared to test his ability acquired so far by presenting a civil case of his father in the court. That was the first opportunity he got to express his talents in speaking to a group of learned people and that was a great success. Gradually, he gained confidence in public speaking and used every opportunity he got to speak. From a weak stammering boy he transformed himself to the greatest orator of ancient Greece.
Demosthenes leaves us a message that if you have a strong passion for becoming an orator, nothing can prevent you from that. You can overcome your shortcomings and fear for public speaking by consistent hard work and regular practice.
Winston Churchill
“Of all the talents bestowed upon men, none is as precious as the gift of oratory. He who enjoys it wields a power more durable than that of a great king”.

Throughout his life, he tried his best to sharpen his talents in the art and craft of public speaking.
Churchill used some classical techniques to make his speeches powerful and memorable. He used to choose his words with utmost care to infuse his speech with a beautiful musical rhythm and resonance. He wrote his speeches and even practiced in front of a mirror before appearing in the British Parliament. He was very careful, about his body postures and gestures and facial expressions. He spoke with simplicity and clarity using lucid language but used some rhetorical techniques to make his speeches inspirational and unique.
Adolf Hitler
Adolf Hitler was born with a gift of gab and is considered as one of the most powerful and effective speakers in history. It was his oratory skill and its excellence that helped Hitler rise to power. His powerful speeches persuaded millions to accept his ideas and stand enthused to follow him. His aggressive style and body language inspired, activated and electrified the audience.
Hitler actually acquired his oratory skills by consistent efforts and practice. In his earlier days, he got a chance to speak to the customers in a bar and beer garden. He used some special techniques to get the attention of the customers who were fully engaged in drinking alcohol. With the help of a photographer, he analyzed and evaluated his different gestures and body positions during his speech. Before becoming the chancellor of Germany itself, he had become a powerful orator.
Hitler believed that powerful public speaking is the most important recipe to change the world. He wrote all speeches himself and edited it several times improvising each time. Hitler used to rehearse his delivery with hand gestures in front of a mirror. He also practiced several breathing exercises for improving his oratory.
Hitler’s speeches were highly dramatic and emotional so that they animated and moved the people as he intended.
John F. Kennedy
John F. Kennedy is regarded as one of the most powerful public speakers in recent history. He used to prepare important speeches well in advance. He used keywords selectively for impressing and inspiring his audience. His youthful handsome appearance and energetic body language was an added advantage for him to impress the people.
It was from 1960, the U.S. presidential debates were shown in TV channels. The open debate between the then presidential candidates Kennedy and Nixon was keenly watched by a great number of people on TV and they were impressed by the performance of Kennedy and opted to vote for him. The people who heard the debate through radio opined and predicted that Nixon will win. The victory of Kennedy as the 35th president of U.S.A proved that the visual effect is a determining factor in the success in public debates and speeches.
Kennedy was very much interested in improving and brushing up his oratory skills. He developed strategies for the speeches by adopting attractive and powerful techniques of the great orators of history. He was a true fan of Abraham Lincoln and found time to read through many of his famous speeches. He was trying to visualize how those words impacted a great lot of people. Kennedy was also careful about choosing the most suitable words to create a sense of community and trust in the people. He truly believed that it is not what you say but how you say is more important for the success in public speaking.
Martin Luther King Jr.
Martin Luther King Jr. is generally accepted as an icon of oratory in history. His, “I have a dream…..” speech became the most famous and enduring speech of all times. A number of great lessons of oratory can be learned from this master speaker.
King’s experience as a Baptist preacher gave him the skill of the classical use of prose rhythm. He made his speeches enduring and powerful by focusing on important moral issues.
King spoke to the hearts of people; his words appealed to their imagination and not just to the intellect. If you carefully watch his speech videos, you can see that he used the phrase ‘I have a dream’ 12 times during his speech. His mesmerizing tone and rhythm made the feeling that he was not simply speaking but, singing the lines of poetry. He modulated his voice by speaking from the diaphragm, instead of the throat. He spoke in slow pitch with radiating confidence and used silence or pauses to make his point memorable.
Martin Luther King Jr. drew inspiration from Shakespeare, the Bible, and numerous civil rights thinkers, in writing his “I have dream” speech. He spent a lot of time to write and rewrite, to edit and re-edit the speech to make it more powerful and motivational.
