 When twenty-three-year-old Carrie Prudence Winter caught her first glimpse of Honolulu from aboard the Zealandia in October 1890, she had "never seen anything so beautiful." She had been traveling for two months since leaving her family home in Connecticut and was at last only a few miles from her final destination, Kawaiaha'o Female Seminary, a flourishing boarding school for Hawaiian girls. As the daughter of staunch New England Congregationalists, Winter had dreamed of being a missionary teacher as a child and reasoned that "teaching for a few years among the Sandwich Islands seemed particularly attractive" while her fiancé pursued a science degree. During her three years at Kawaiaha'o, Winter wrote often and at length to her "beloved Charlie"; her lively and affectionate letters provide readers with not only an intimate look at nineteenth-century courtship, but many invaluable details about life in Hawai'i during the last years of the monarchy and a young woman's struggle to enter a career while adjusting to surroundings that were unlike anything she had ever experienced.
In generous excerpts from dozens of letters, Winter describes teaching and living with her pupils, her relationships with fellow teachers, and her encounters with Hawaiian royalty (in particular Kawaiaha'o enjoyed the patronage of Queen Lili'uokalani, whose adopted daughter was enrolled as a pupil) and members of influential missionary families, as well as ordinary citizens. She discusses the serious health concerns (leprosy, smallpox, malaria) that irrevocably affected the lives of her students and took a keen (if somewhat naive) interest in relaying the political turmoil that ended in the annexation of the Hawaiian Islands by the U.S. in 1898.
The book opens with a magazine article written by Winter and published while she was still teaching at Kawaiaha'o, which humorously recounts her journey from Connecticut to Hawai'i and her arrival at the seminary. The work is augmented by more than fifty photographs, four autobiographical student essays, and an appendix identifying all of Winter's students and others mentioned in the letters. A foreword by education historian C. Kalani Beyer provides a context for understanding the Euro-centric and assimilationist curriculum promoted by early schools for Hawaiians like Kawaiaha'o Female Seminary and later the Kamehameha Schools and Mid-Pacific Institute.

NEW BOOK! THE SUGAR KING OF CALIFORNIA: The life of Claus Spreckels  2024 


San Francisco occupies the tip of a peninsula, the thumb of grasping hand around a storied bay. Anyone who deeply examines the history of the city begins to suspect the print of that thumb belongs to 19th Century 'sugar king,' Claus Spreckels. More than a century after his death, the mark of this blue-collar tycoon can still be found in almost every square mile of San Francisco.
-Woody LaBounty, President & CEO of San Francisco Heritage
Anyone making a shortlist (however short the list) of the most important people that influenced the development of Hawai'i in the late-19th century has to include Claus Spreckels.  Sugar, and the 'Sugar King,' changed the economic and social make-up of the Hawaiian Islands, and Bonura takes us through the journey of his life, and the profound legacy he left. 
-Peter T. Young, Designated Living Treasure of Hawaii in 2023 and President of Hoʻokuleana LLC 
An amazing man and an amazing woman. There was nothing small about Claus Spreckels. Everything that he did was on the grandest scale. He saw opportunities everywhere. He became the richest man in California. On California's Monterey Bay he built the largest and finest summer resort in the state where he hosted the Inauguration Ball for Governor Pacheco. He brought the railroad and built the largest beet sugar refinery in the world. He was visited by royalty. He was famous in his time but largely unsung today. The amazing woman is Sandra Bonura who had the fortitude to research and write this amazing untold story.
-John Hibble, President, Aptos Chamber of Commerce and curator of the Aptos History Museum
This book gives a taste of the American dream, lived by a poor German farmhand, who became one of those mythical figures, who created modern California: Bonura presents Claus Spreckels' life full of work, rude business methods, luck and, eventually, moderation – and combines this with a touching history of his private life.
-Uwe Spiekermann, former deputy director of the German Historical Institute in Washington DC. Author of multiple works on the economic and social history of immigrants to the United States in the 19th and 20th Century.
 Imagine 150 years from now that no one had written the comprehensive history of Elon Musk. Dr. Sandra Bonura is the first biographer to give a heart and soul to Claus Spreckels,  his era's Musk. Fiercely independent, resourceful and combative, Spreckels arguably altered the history of California more than anyone in his time. Deeply researched, Bonura paints a complete tapestry of Claus' complicated business and family life, wealth beyond imagination, and the incredible drive of a titan without peer. Sugar King is a great companion to Empire Builder, her John D. Spreckels biography.

'Empire Builder' explores the legacy of John D. Spreckels, the man who built San Diego

Sandra Bonura's new book, 'Empire Builder: John D. Spreckels and the Making of San Diego,' reveals the man behind the city
He died in 1926, almost 30 years before she was born. But like many native San Diegans who came before and after her, Sandra Bonura grew up in the world John D. Spreckels built.
Bonura's mother worked on Coronado Island, where — at one time or another during his late 19th- and early 20th-century heyday — Spreckels had owned North Island, the San Diego-Coronado Ferry System, the Coronado Beach Company and the Hotel Del Coronado. As a girl, Bonura often spent weekends with her grandmother at the Hotel Metropole boarding house, where she could see the marquee of the grand Spreckels Theater from the lobby window. From her grandmother's second-floor room, Bonura had a fine view of what used to be D Street, which Spreckels renamed Broadway and developed into a thoroughfare worthy of six of his own buildings.


But before he was the man who gave San Diego electric streetcars, its first skyscraper and the Spreckels Organ Pavilion, John D. Spreckels was the son of a hardworking German immigrant, a rebellious son who left the family's booming sugar business to make his mark on a nowhere town that he loved at first sight. It was that John D. Spreckels — the man with the humble German roots and the immigrant work ethic — who convinced author Bonura that the story of the other John D. Spreckels — the powerful, ambitious man who put San Diego on multiple maps — was a tale she could tell.
With her new biography, "Empire Builder: John D. Spreckels and the Making of San Diego," Bonura hopes to do justice to both of them.


Born in 1853 in Charleston, S.C., John Diedrich Spreckels was never going to be a man who thought small. His German-born father started his American life working in a New York grocery store. He moved his family to San Francisco, and after opening a few breweries, Claus got into the sugar-refining business. By 1880, the Spreckels California Sugar Refinery was producing 50 million pounds of sugar a year, and Claus Spreckels was on his way to being named one of the richest men in the world.


In "Empire Builder," Bonura shows that one of costs of being Claus' oldest son was a shortchanged childhood. At 10, John was pulled away from school and his beloved piano lessons to accompany Claus on a fact-finding trip to New York. By the time he was 13, John was listed as the company's vice president.
"Originally I thought, 'I'm not going to like this guy at all.' He seemed so brutal and antagonistic," Bonura said from her home in Del Cerro. "But the more I learned about him, the more I saw what he sacrificed. He didn't want to be in the sugar business, but he was the vice president of his father's company at 13. Where was his childhood? "
John may have preferred a different career, but as his brothers Adolph B., Claus A. (nicknamed "Gus") and Rudolph also found out, being part of the Spreckels sugar empire was not optional. And as the family embarked on a lucrative and controversial expansion into Hawaii, John honed the aggressive, uncompromising business style that would serve him well once he found something that he really wanted.Just one month before his 34th birthday, John D. Spreckels found that something. And it was us. 


Spreckels' first glimpse of his future came in July of 1887, when he sailed his yacht into San Diego Bay to find a small town in the midst of a frenzied land boom. With encouragement from brash young developer Elisha Spurr Babcock Jr., Spreckels built San Diego a new wharf and coal bunker, which would help spur San Diego's growth while fortuitously benefiting Spreckels' thriving shipping business.
Thanks to his ability to ride out the land bust of 1888, the sugar prince used the family's power and his own considerable wealth and business prowess to make San Diego his own. 
And in the process, he made San Diego.


"If you are looking at the period from the 1880s through the 1920s, Spreckels was the single most important person in driving growth in the city," said Andy Strathman, a lecturer in Cal State San Marcos' history department and the co-editor of the Journal of San Diego History, which is published by the San Diego History Center.
"One way to envision what Spreckels meant to San Diego generally is that he could get up in the morning in his home on Coronado, take the Spreckels ferry to San Diego, disembark at the Spreckels wharf and walk down Broadway, which was his little stretch of San Diego. He owned the San Diego Union and the Tribune. He was responsible for naming Broadway. That is how much he was responsible for that growth."
Quiet titan
In keeping with the title of her book, Bonura chronicles the building of Spreckels' San Diego Empire, which came to include the San Diego Union and Tribune newspapers, the San Diego Electric Railway, the San Diego and Arizona Railway, and Belmont Park. He helped bring the 1915 Panama-California Exposition to Balboa Park. He created the zoo's first elephant enclosure. 
But a formidable subject like John D. Spreckels deserves an intrepid biographer, and if anyone was going to get to the heart of the man behind the buildings, it was going to be Bonura.


Bonura is also a history buff and a writer, two loves that she combined to write her first two books. Her 2012 book — "An American Girl in the Hawaiian Islands: Letters of Carrie Prudence Winter, 1890-1893" — looked at life in Hawaii during the last years of the monarchy through the letters of a young teacher. Her 2017 book, "Light in the Queen's Garden," told the true story of Ida May Pope, an Oberlin College-educated teacher and activist who played a surprising role in Hawaiian history during the 1893 Hawaiian Revolution and beyond.
While Bonura was doing her deep-diving research into Pope's life, she discovered that John D. Spreckels — the man from the theater marquee of her San Diego childhood — had been a close friend of Hawaii's Queen Lili'uokalani. In the process of satisfying her curiosity about this unlikely connection, Bonura amassed enough new research — diaries, oral histories, many personal photos and records from Spreckels' surviving family members — to curate a 2018 exhibit for the Coronado Historical Association's museum. 


That exhibit kickstarted what would become "Empire Builder," a 440-page book that looks at both the empire and the man. In addition to Spreckels' many achievements, we hear about the cutthroat deals, the lawsuits, the brawling family dramas and the controversial power plays that only a man with his outsized influence could pull off. 
We also hear about Spreckels' love of family and music. We hear how he gave Coronado its first library and San Diego its first Japanese gardens. We see him as the philanthropist who avoided the spotlight and the titan who was deathly afraid of public speaking. 


Ultimately, we see the many sides of the man who saw San Diego as town with the potential to become so much more. The man who was determined to get us there. 


"People would be amazed at the lengths he went to to build San Diego and to employ its inhabitants and to give people are reason to get up in the morning and do things. Everything he did made life easier for people. He even gave them Mission Beach, which made life fun." said Spreckels' great-granddaughter Virginia Wilson, who lives in Napa County and provided Bonura with many family records and mementos. 
"He gave his life for San Diego, and I don't want his legacy to be forgotten. That is what is so important to me about this book."

Light in the Queen's Garden: Ida May Pope, Pioneer for Hawai'i's Daughters, 1862–1914 is an historical account of a woman from the heartland of America who landed in the Kingdom of Hawai`i at the end of the 19th century. When young Oberlin graduate, Ida Pope accepted a "temporary" teaching job in a boarding school for Hawaiian girls, founded by American missionaries and led by Queen Lili'uokalani, she couldn't have imagined it would become a lifelong career of service to Hawaiian women. Nor could she have envisioned she would become closely involved in the greatest political turmoil the Hawaiians had ever experienced.


Newly discovered primary sources are used to flesh out and enliven the historical account of the 1893 Hawaiian Revolution that happened literally outside the school's windows. A day-by-day accounting of the events surrounding the coup d'état through the eyes of Pope's young pupils is offered for the first time. Lili'uokalani's adopted daughter's long-lost oral history recording, many of Pope's teaching contemporaries' unpublished diaries, letters, scrapbooks and photos tell a story that has never been told before.


Towering royal personages in Hawai`i's history, King Kalākaua, Queen Lili`uokalani, Princess Ka`iulani and others, appear as Pope sheltered Hawai`i's daughters through the frightening and turbulent end of their sovereign nation. Pope was present during the life celebrations of the king, and then his sad death rituals. She then had the extraordinary opportunity to travel with the queen on her controversial trip to Kalaupapa's "Leper Colony" to visit Saint Marianne Cope and afflicted pupils.


Pope became a source of inspiration for Hawai`i's educational leaders and with the endorsement of Lili`uokalani and Charles Bishop, established the Kamehameha School for Girls in 1894 funded by the estate of Princess Pauahi Bishop, the last of the royal Kamehameha line. Pope furthered her own education with courses at the University of Chicago. Inspired by John Dewey and others, she shaped and reshaped Kamehameha's curriculum through a process of conflict and compromise. Fired up by the era's doctrine of social and vocational relevance, she adapted the curriculum to prepare her students for entry into meaningful careers. Lili`uokalani's daughter, Lydia Kaʻonohiponiponiokalani Aholo, was placed in the school and Pope played a significant role in mothering and shaping her future, especially during the years the queen was fighting to restore her kingdom.  


As Hawai`i moved into the 20th century under a new flag, Ida tenaciously confronted the effects of industrialization, the growing concentration of outside economic power and worked tirelessly to attain social reforms to give Hawaiian women their rightful place in society. But, the male-dominated society and their Victorian view of the female role sought to thwart her efforts. Undaunted, Pope, the pragmatic activist, achieved on a small island in the middle of the Pacific Ocean, what other extraordinary women like Jane Addams, Ida Tarbell and Lillian Wald did concurrently in her homeland.
