Lafayette Frederick

Lafayette Frederick was a plant pathologist and mycologist whose research focused on fungal disease of plants, spore development of fungi and the systematics and ecology of acellular slime molds. He was born March 9, 1923, in Dog Bog, Mississippi, and passed away on Dec. 29, 2018.

Here are five things to know about Lafayette Frederick:

1. Interest in Botany

At a young age, Lafayette was exposed to plants and the natural world, growing up on a variety of sharecropper farms. But his interest in botany started as an undergraduate student at Tuskegee Institute (now Tuskegee University) where he was inspired by the famous botanist and plant chemist Dr. George Washington Carver.

2. Drafted to the War

During World War II, Lafayette was drafted into the U.S. Navy, which took him to Hawaii. He stayed in the Aloha State as a civilian after his duties and spent two years as a part-time graduate student at the University of Hawaii, collecting and identifying native Hawaiian plants. It was there he met a mycologist, a researcher who works with fungi and studies the diversity and evolution of mushroom-forming fungi, who inspired his career.

3. His work

Lafayette worked on several projects that involved research on antifungal substances of strain of bacterium. He worked and chaired at several colleges, including Southern University, Atlanta University and Howard University. He also was responsible for integrating the Association of Southeastern Biologists meeting, which did not allow its African American members to attend.

4. Plant Named After Him

There is a species of Hawaiian shrub, Cyrtandra Frederickii, named after Lafayette by Harold St. John, former chairman of the University of Hawaii department of botany.

5. Legacy

His legacy was characterized by supporting and mentoring students, progressing the value of equality and integration, and furthering the progress of scientific discovery.

Dr. Thomas Walter Gaither

Thomas Walter Gaither is a Civil Rights activist and biologist. He was born in Great Falls, South Carolina. He taught biology at Slippery Rock University for almost four decades. He earned a Ph.D. degree in biology from the University of Iowa. But his career was distinguished by his civil rights work. 

Here are five things to know about Dr. Thomas Walter Gaither: 

1. Parents Were Teachers

Thomas grew up the son of two teachers in the segregated south. His father resigned in protest after realizing he was being paid less than his contract said, and less than his white colleagues. At a young age, he grew up in a household where education and the fight for equality were both important. 

2. Civil Rights Work Started in College

He attended Claflin College and lead the college’s National Association for the Advancement of Colored People (NAACP) chapter.

3. Was Arrested for His Civil Rights Activist

During his time in college, Thomas organized a sit-in at a segregated diner in South Carolina. He recruited eight other men who would later be known as the “Friendship Nine.” The men were arrested and charged with trespassing. A judge sentenced the group to either a $100 fine or 30 days of hard labor. The group of men chose the latter as a form of protest that ushered the “Jail, no bail” movement that oppose giving money to governments supporting Jim Crow laws. After their release, Thomas started organizing with the Congress of Racial Equality (CORE) for the 1961 Freedom Rides.

4. Served in the Military

Thomas’ work as a central organizer for civil rights ended when he was drafted into the army. Because of his history of civil rights-related arrests, he was determined ‘lacking in moral character’ and was able to return to school.

5. Has a Scholarship Named After Him

In 1968, he joined Slippery Rock University, teaching biology until he retired in 2007. The college honored him with an award for his work creating diversity on campus and created a scholarship in his name. The Thomas W. Gaither Scholarship offers $1,000 annually for an entering student majoring in biology with the intention of becoming a professional biologist, biology teacher or entering the medical field.

Dionne Washington 

In late 2019, cofounders Dionne Washington and Bridget Pettis launched Project Roots, a Phoenix-based nonprofit that is helping underserved communities grow their own food and offers a seasonal produce bag delivery service. Project Roots also provides food boxes to those in need and those experiencing homelessness. The nonprofit has a community farm at Spaces of Opportunity, a Garden partner.

Here are five things to know about Dionne Washington:

1. Started Growing Tomatoes

Cofounders Dionne and Bridget started growing tomatoes at a now defunct community farm. They grew 50-foot rows of tomatoes. After growing a surplus of tomatoes, the pair decided to offer them to communities and other organizations for free. Then, they started to make soup from the extra tomatoes. “We decided we could do something special. We could grow our own food. We could give that food away to people who need it. And that’s how Project Roots started,” Dionne says.

2. Business Partner was a former Phoenix Mercury player

Dionne’s business partner is former Phoenix Mercury player Bridget Pettis. While Dionne focuses on the business operation side of the nonprofit, Bridget spends her time among the row of produce Project Roots grows at Spaces of Opportunity, where they have been for two years now.

3. Was a Business Owner

Before partnering with Bridget, Dionne ran her own business and earned her MBA in October 2021.

4. Mobile Food Delivery Service

Starting March 1, Project Roots will use a truck for its mobile delivery service of its seasonal produce. The nonprofit currently delivers produce bags, but with the help of a grant last year, Project Roots will be able to use a truck to streamline and increase access to its delivery service. Dionne says the organization is currently fundraising to purchase its own truck for next year. You can help out Project Roots in a number of ways. Sign up to volunteer, donate land or donate online.

5. Most Proud Moment

Dionne is really proud of people and partners who have helped build awareness of Project Roots. “I’m most proud of the people who have come together to activate our community and let them know we are here for them. We’ve done an excellent job, and I think it’s because of our partners at Spaces of Opportunity, Desert Botanical Garden and people who come to our classes. I’m proud of my team and the growth that has gotten us here.”

Abra Lee

Georgia native Abra Lee is a horticulturalist who over the course of career developed a passion to share the stories of Black Americans and their contributions to the industry and the American landscape.

Growing up listening to stories of grandparents and elders, Abra was inspired by the generations than came before her and saw a need to retell those stories to inspired and educate generations to come. She earned a degree in ornamental horticulture from Auburn University. She has a book about the topic “Conquer the Soil,” which is set to be published in early 2023.

Here are five things to know Abra Lee:

1. Interest in Horticulture

Abra grew up in Atlanta but would spend her weekends at her aunt’s in rural Barnesville, Georgia. Her dad was director of parks for Atlanta. She also spent weekends visiting parks throughout the city. Abra gained an interest in horticulture after watching horticulture students studying a sugar maple tree at Auburn University. 

 2. Horticulture Work

During college, Abra had internship as an estate gardener in Atlanta, which exposed her to high level of horticultural artisanship. She maintained lawns of NFL owners. Later in her career, she was landscape manager for Hartsfield-Jackson Atlanta International Airport and George Bush Intercontinental Airport and served as a county extension agent with the University of Georgia. During 2019 to 2020, she was part of the Longwood Gardens fellowship, a prestigious leader-development program sponsored by the garden.

 3. Her Interest in Black Garden History

Abra’s mom, who was an educator, gave her a book that told the story of how Auburn University would sneak George Washington Carver at night to teach professors. This sparked her curiosity to further look into these stories and share them to the public. “I was very much deeply making it my life’s purpose to finding these stories and rich history because it was exciting to me and certainly motivating,” Abra says. She created a social media account that highlights these figures and has also been asked to speak about the topic at several botanical gardens and institutions across the country.

4. Does Her Own Research

When Abra started digging in to these stories, she was reading several pieces of literature from W.E.B. Du Bois to civil rights and social justice icons. “In The Souls of Black Folk,’” Du Bois talks about the three gifts Black people brought to the Americas. He talked about the gift of spirit, story/ song and their gift of what he called strength and brawn, which was their ability to conquer the soil. The words jumped out the page. That’s who I am. That’s what Conquer the Soil is,” Abra says. This independent research helps her retell stories of historical figures and put them in perspective in our current time.

5. Has a Book Coming Out in 2023

Abra, who started sharing Black Garden History since 2010, has a book coming out titled ‘Conquer the Soil,’ which spotlights figures that enriches the public’s understanding of the history of horticulture. The book is set to come out January 2023.
