Abstract

Harold C. Fritts [known to many as “Hal”] passed away at his home in Tucson, Arizona, on January 10, 2019, at the age of 90. Hal was born December 17, 1928, in Rochester, New York, and was raised in the town of Pittsford where he developed a growing interest in nature. He attended Pittsford High School where he graduated as class salutatorian in 1947. Hal then enrolled at Oberlin College in Ohio where he earned his B.A. degree in 1951. Hal went on to graduate school at Ohio State University in Columbus, where he was awarded his M.Sc. in 1953 (Thesis:Radial Growth of Beech Trees in a Central Ohio Forest during 1952) and Ph.D. in 1956 (Dissertation: Relations of Radial Growth of Beech (Fagus grandifolia Ehrh.) to Some Environmental Factors in a Central Ohio Forest during 1954-55), both in botany. The primary instrument of his dissertation research was the “dendrograph” [named the Fritts-Dendrograph], developed with the help of his father, an engineer. One year before completing his Ph.D. Hal married his first wife Barbara June Smith. Hal took his first academic post as Assistant Professor at Eastern Illinois University in 1956. In 1960, he was appointed Assistant Professor of Dendrochronology at the University of Arizona, Laboratory of Tree-Ring Research (LTRR). His hire followed not long after the untimely death of LTRR Prof. Edmund Schulman in 1958. His early work examined intraand inter-annual treering growth of western conifers, aided by his dendrographs and cambial sampling. Moreover, he developed conceptual models of how various environmental factors could influence cell formation, maturation, and ring size, and eventually he began developing computer models of growth. This culminated in an advanced process model, TREERING, developed with Russian colleagues. These collective activities are tied to one of Hal’s enduring contributions to dendrochronology, namely that he injected scientific and computational rigor into the field and provided convincing quantitative validation to the underpinnings of dendrochronological principles.

哈罗德·C·弗里茨（被许多人称为“哈尔”）于2019年1月10日在亚利桑那州图森市的家中去世，享年90岁。哈尔1928年12月17日出生于纽约州罗切斯特市，在匹兹堡长大，在那里他对自然产生了越来越大的兴趣。他就读于皮茨福德高中，1947年毕业于该校，担任班主任。哈尔随后就读于俄亥俄州的奥伯林学院，1951年在那里获得了学士学位。哈尔后来在哥伦布的俄亥俄州立大学读研究生，1953年获得植物学硕士学位（论文：1952年俄亥俄州中部森林中山毛榉的径向生长），1956年获得博士学位（论文《1954-55年俄亥俄州部森林中山毛榉的径向生长与一些环境因素的关系》）。他的论文研究的主要工具是“树状图”（名为弗里茨树状图），是在他父亲（一名工程师）的帮助下开发的。在完成博士学位的前一年，哈尔娶了他的第一任妻子芭芭拉·琼·史密斯。哈尔于1956年在东伊利诺伊大学担任助理教授，这是他的第一个学术职位。1960年，他被任命为亚利桑那大学树木年轮研究实验室的树木年表助理教授。1958年LTRR教授Edmund Schulman英年早逝后不久，他就被聘用了。他的早期工作在树状图和形成层取样的帮助下，研究了西部针叶树的年内和年间年轮生长。此外，他开发了各种环境因素如何影响细胞形成、成熟和环大小的概念模型，最终他开始开发生长的计算机模型。这最终导致了与俄罗斯同事共同开发的先进工艺模型TREERING。这些集体活动与哈尔对树木年代学的一项持久贡献有关，即他为该领域注入了科学和计算的严谨性，并为树木年代学原理的基础提供了令人信服的定量验证。为此，哈尔还介绍

期刊介绍： Tree-Ring Research (TRR) is devoted to papers dealing with the growth rings of trees and the applications of tree-ring research in a wide variety of fields, including but not limited to archaeology, geology, ecology, hydrology, climatology, forestry, and botany. Papers involving research results, new techniques of data acquisition or analysis, and regional or subject-oriented reviews or syntheses are considered for publication. Scientific papers usually fall into two main categories. Articles should not exceed 5000 words, or approximately 20 double-spaced typewritten pages, including tables, references, and an abstract of 200 words or fewer. All manuscripts submitted as Articles are reviewed by at least two referees. Research Reports, which are usually reviewed by at least one outside referee, should not exceed 1500 words or include more than two figures. Research Reports address technical developments, describe well-documented but preliminary research results, or present findings for which the Article format is not appropriate. Book or monograph Reviews of 500 words or less are also considered. Other categories of papers are occasionally published. All papers are published only in English. Abstracts of the Articles or Reports may be printed in other languages if supplied by the author(s) with English translations.
