Baroness Bertha Sophie Felicitas von Suttner, also known as Bertha von Suttner, was an Austro-Bohemian noblewoman, pacifist, and renowned novelist. Born on June 9, 1843, in Prague, she made history by becoming the second female Nobel laureate and the first woman to receive the Nobel Peace Prize in 1905. Bertha overcame societal challenges, facing exclusion from the Austrian high nobility due to her "mixed" descent, and limited financial resources from her father. Despite these obstacles, she pursued an education in literature, philosophy, and languages, becoming proficient in French, Italian, and English. Bertha also cultivated her talents as an amateur pianist and singer. Her early engagements and encounters with prominent figures, such as Tsar Alexander II, shaped her aspirations, leading her to pursue a career as an opera singer. However, her stage fright and inability to secure professional engagements steered her towards a different path. Bertha von Suttner's dedication to peace advocacy and literary contributions have left an indelible mark on history, inspiring future generations with her remarkable achievements and unwavering commitment to promoting peace.

Bertha Alice Williams Graham Gifford, born on October 30, 1871, was a farmwife in rural Catawissa, Missouri, during the early 1900s. Accused of murdering three members of the local community and suspected in 15 additional deaths, she is considered by some as America's fifth solo female serial killer. Born in Morse Mill, Missouri, she was one of 10 children and married to Henry Graham, with whom she had one daughter, Lila. After Graham's death, she married Eugene Gifford, with whom she had one child, James.Gifford's notoriety stemmed from her cooking skills and care for sick neighbors and relatives, yet five people died in her care, leading to a grand jury investigation. In 1928, she was arrested and charged with three murders, and subsequent examinations revealed large amounts of arsenic in the bodies. Despite the three-day trial resulting in a verdict of not guilty by reason of insanity, she was committed to a psychiatric institution until her death in 1951. Gifford's role as a nurse to her sick neighbors saw a total of 17 people die in her care, with suspicions raised about an additional 12 deaths following a grand jury investigation. Given the high mortality rates and the amateur use of arsenic for medical reasons at the time, uncertainty remains about whether she purposefully killed everyone under her care.

Bertha, also known as Aldeberge, was a Frankish princess who became the queen of Kent during the 6th century. She played a significant role in enabling the 597 Gregorian mission led by Augustine, which resulted in the conversion of Anglo-Saxon England to Christianity. Bertha's marriage to the pagan Æthelberht of Kent in 580 was conditional upon her freedom to practice her Christian faith. She brought her chaplain, Liudhard, with her to England and restored a former Roman church just outside Canterbury, which was dedicated to Martin of Tours. This church, known as St Martin's Church, is recognized by UNESCO as the oldest continuously used Christian worship site in the English-speaking world. Bertha's influence and Æthelberht's goodwill were crucial in the establishment of monastic settlements and the cathedral in Canterbury. She is acknowledged for her faith and knowledge of letters, and she is believed to have had two children, Eadbald of Kent and Æthelburg of Kent. The legacy of Queen Bertha is celebrated in the City of Canterbury through the Bertha trail and bronze statues commemorating her and Æthelberht. Her exact date of death is disputed, but her impact on the spread of Christianity in England is undeniable.
